    2.1.5.2 Serial port (COM1, 2) The IT8673 incorporates the two 16C550 compatible serial port controllers (UART1 and UART2). The 24MHz signal (fixed) is 13-frequency-divided into 1.8462MHz that is then used to produce a Baud rate clock. This port operates in an asynchronous mode. The two controllers are independent of each other.
  • Page 49 The I/O levels of the UART1,2 signals of the IT8673F1 are maintained at the TTL level. The ADM211 is used outside the UART2 for use as the driver or receiver of the RS-232-C interface. The ADM211 is an IC of 4 outputs and 5 inputs, and works only with a single power supply of +5V.
  • Page 50: Parallel Port Interface Circuit

    2.1.5.3 Parallel port interface circuit The IT8673F is used as a parallel port control. The parallel port of the IT8673F has a both-way function. When controlled by software, the data signals of the PD7-PD0 become both-way signals. The output signals (SLIN, INIT, AFD, STB) for parallel port control are pulled up with 4.7kΩ of open drain output. However, since they are connected to the power supply terminal through diodes, Device 74LS07 is inserted at an external open collector buffer.

    2.1.5.4 FDD interface circuit The IT8673F is used as a floppy disc controller. The FDC functions of the IT8673F are compatible with Devices 765A, DP8473. The interface circuit is made AT-compatible. All the output signals to the FDD are processed in the open collector mode, pulled up with 1kΩ. All the input signals from the FDD are pulled up with 2.2kΩ.
  • Page 52 [Outline Operation of FDD] As an outline operation, an FDD is selected to make the motor run, provided that the signals of both DRV0# and MTR0# are set at the low level. Each time the motor makes one revolution, an input of INDEX# signal is generated. This signal is used to identify that a diskette is present.
  • Page 53: Keyboard Controller Circuit

    2.1.5.5 Keyboard controller circuit The IT8673F is used for keyboard control. The internal memory block of the IT8673F has programs for the keyboard control and the control with the main CPU. The IT8673F internally converts the serial data sent from the keyboard into parallel data, and performs interrupt operation to inform the CPU of the entry of a key input.
  • Page 54 The transistor circuit is intended to control signals of the keyboard and the magnetic card controller. Control is actually undertaken by the magnetic card controller. When the anodes of the diodes D_A and D_B are maintained at the high level, the transistors of Q_A~Q_D104 are turned ON and the keyboard signals are led to the keyboard controller.
