  • Page 6: Overview

    1: OVERVIEW VERVIEW The S1D13700 Controller displays text and graphics on a midsize, dot-matrix liquid crystal display (LCD). A very flexible, low-power display system can be configured using the S1D13700 in combination with various LCD modules. The character code or bitmap display data from the microprocessor is temporarily stored in frame buffer memory, then periodically read out and converted into LCD module signals for output to the LCD.

  • Page 7: System Overview

    32 Kbytes of internal display memory (VRAM). Moreover, because the S1D13700 has a built-in a control circuit for LCD units, it is possible to take full advantage of the features of midsize, dot-matrix liquid crystal display units without using any external circuit.

    MPU. Therefore, the MPU does not need to frequently check the status of the S1D13700, and is not kept waiting by the S1D13700. Thus, the high-speed interfacing method adopted for the S1D13700 helps minimize possible reduction in the MPU’s processing capability.

    The RESET# input is used to initially reset the S1D13700 in hardware. Note 4 Note 4: Although this pin is a Schmitt trigger input to prevent the S1D13700 from being inavertently reset by noise, care must be taken when intentionally lowering the power supply voltage.

  • Page 18: Lcd Driver Control Pins

    2.2.4 LCD Driver Control Pins The S1D13700 can directly control both the X and Y drivers based on an enable chain, which is a method of effectively reducing the amount of current consumption needed to drive dot-matrix liquid crystal display elements.

  • Page 19: Commands And Command Registers

    Note 1: As a rule, each command is executed every time a parameter for the command is input to the S1D13700, and completed before the next parameter (P) or command (C) is input. Therefore, the MPU can stop sending parameters in the middle and send the next command. In this case, the parameters that have already been sent are effective and other parameters not input to the S1D13700 retain their original values.

    * The S1D13700 ignores any attempt to access address space 8030h–FFFFh. This address space may be employed as a user area, but because there is no negate output available for the WAIT# pin of the S1D13700, inhibit access to this address space when not in use.

  • Page 22: Command Description

    This command and the parameters that follow specify initial reset of the device, set the window size, and the method of connecting with the LCD unit. This command determines the fundamental operation of the S1D13700. Therefore, if this command is incorrectly set, the functions of other commands may not work normally.

    However, because the character origin is at the upper-left corner of the screen when characters are mapped on the screen by the S1D13700, the uppermost line and leftmost column on the display screen do not have dots to draw the outline of characters, thus making the displayed characters illegible.

    • • SLEEP IN When this command is input, the S1D13700 blanks the display for at least a one-frame period, then stops all internal operations including clock oscillation before entering sleep mode. At this time, the LCD unit sends OFF data to the X driver while simultaneously sending the YDIS signal to the Y driver to turn the bias voltage off.

  • Page 30: Display Control Commands

    2. If the drive power supply of the liquid crystal remains on in sleep mode, a DC component may be applied to the LCD panel because all internal operations of the S1D13700 have been stopped in that mode. When priority is placed on reliability, however, the liquid crystal drive power supply must be turned off before writing the sleep command to prevent DC com- ponents from being applied to the LCD panel.

    This command is used to read a cursor address from the cursor register.When this command is written to the S1D13700, the low-order byte of the cursor address (CSRL) is set in the output buffer. Therefore, the high-order byte of the cursor address (CSRH) also can be read out by entering the RD signal following this command.

  • Page 49: Memory Control Commands

    Memory Control Commands MWRITE This command is used by the MPU to place the S1D13700 in the data input state before writing data to display memory. Each time the WR# signal is input following this command, the S1D13700 automatically modifies the cursor address at which to write display memory according to the CSRDIR value. This allows the MPU to write two or more consecutive items of data to display memory.

  • Page 50: Function Description

    Screen Management (1) Character configuration The S1D13700 can display characters using a row-scanning type of character generator that defines character patterns in the fourth quadrant with respect to the character origin as shown below. Although the character generator used determines the size of the character font area, the size of the character field can be varied in both the X and Y directions.

  • Page 51: Figure 4-3 Example Of Character Configuration Consisting Of Two Or More Memory Addresses (when [fx] = 9)

    Figure 4-3 Example of character configuration consisting of two or more memory addresses (when [FX] = 9) Note 1: The S1D13700 does not automatically insert character spaces. If the character field is great- er than or equal to 9 dots, two memory addresses are required to configure one character even when the character font area may be within 8 dots.

  • Page 52: Character Generator (cg)

    (2) Concept of how character generator banks are set Because the character codes handled by the S1D13700 consist of 8 bits, the number of discrete characters that can be displayed simultaneously is limited to a maximum of 256.

  • Page 66: Cursor

    (3) Cursor display layer Although the S1D13700 can display up to three overlaid layers, the cursor can be displayed in only one of those layers. In other words, the cursor-attribute layer (or layer in which the cursor can be displayed) is: First layer (L1) during two-layer composition, or Third layer (L3) during three-layer composition.

  • Page 67: Relationship Between Display Memory And Screens

    Relationship between Display Memory and Screens The display memory of the S1D13700 may be used as a virtual screen of greater width than the physical size of the LCD panel address range (C/R). One layer of the S1D13700 may be considered a window through which to look at the part of display memory that comprises a virtual screen.

  • Page 69: Determining Various Parameters

    • The display of graphics or text becomes unstable. Should any of the symptoms above be observed, even though the S1D13700’s other signals connected to the LCD unit are normal, check whether the TC/R value is correct. If the TC/R value is the cause of the problem, simply set a larger TC/R value to restore normal operation.

  • Page 70: Scrolling

    This refers to a mode of scroll operation whereby scrolling is performed within display memory space equivalent to one screen. All lines are scrolled one line up and the bottom line is deleted as shown below. Since the S1D13700 does not automatically delete the bottom line, the MPU must rewrite the scroll address registers and simultaneously write blank data to the S1D13700.

  • Page 71

    Note 1: Omnidirectional scrolling in units of dots is possible by using the SCROLL and HDOT SCR commands in combination. Note 2: On a split screen, individual screen blocks cannot be independently scrolled in the X direction in dot units. EPSON S1D13700 Technical Manual...

  • Page 72: Figure 4-10 Example Of Using Hdot Scr ([fx] = 8)

    MPU only needs to sequentially increment the value of the HDOT SCR command parameter (number of dots to be shifted) without modifying the display start address (SAD) in the S1D13700 to shift display leftward one dot at a time. Then when display has been dot-shifted a distance equal to the character field, the MPU should reset the value of the HDOT SCR command parameter to 00H and simultaneously increment SAD by one address.

  • Page 73: Attribute Display Using The Layered Function

    4.1.8 Attribute Display using the Layered Function The S1D13700 provides a means of increasing the ability of expression on a monochrome liquid crystal display. More specifically, it uses the OVLAY and DISP ON/OFF commands to display characters in inverse video, produce halftone menu pads, and flash a given screen area for various highlighting effects as shown below.

  • Page 74

    4: FUNCTION DESCRIPTION (2) Halftone display The S1D13700 uses the DISP ON/OFF command’s FP parameter to produce halftone display. This is accomplished by flashing the screen at 15 Hz. However, because this method of display may cause display to flicker, characteristics of the LCD module used must be carefully considered.

  • Page 75: Oscillator Circuit

    4: FUNCTION DESCRIPTION Oscillator Circuit The S1D13700 features a built-in oscillator circuit, with a resonator connected to the XG and XD pins to generate oscillation. In addition to the crystal resonator, the feedback resistor Rf, drain resistor Rd, and oscillation capacitors CG and CD must be externally connected to the chip. The RC time constant needed to produce stable oscillation varies with the crystal resonator used and condition of the board.

    In indirect interface mode, AB0 generally is connected to the least significant bit of the system address bus. CNF2 and CNF3 are provided for changing the functions of S1D13700 pins 58 and 59 to enable the chip to be connected directly to the 80 or 68-series MPU bus, and are pulled high or low through a resistor when in use.
