  • Page 40: Local Bus Mode

    Local Bus Mode The ÉlanSC310 microcontroller evaluation board provides a proprietary local-bus connector for testing of local-bus designs. Since this connector is not standard, a custom interface is required to test the local-bus functionality of the ÉlanSC310 microcontroller on the evaluation board. In Local Bus mode, some of the ISA bus signals are lost.

  • Page 42: I/O

    The ÉlanSC310 microcontroller integrates several standard I/O interfaces. A 16C450-compatible UART, bidirectional parallel port is controlled by the ÉlanSC310 microcontroller. In addition, the ÉlanSC310 microcontroller evaluation board contains a Super I/O, which contains a 16C550 UART, a floppy disk controller, and IDE hard drive interface. A standard 9-pin connector is provided for an extended PC keyboard.

  • Page 46: Bl1-Bl4 Pins

    BL1–BL4 Pins These signals are used to indicate the current status of the battery to the ÉlanSC310 microcontroller. A high signal indicates normal operating conditions, while a low indicates a warning condition. Access to these signals has been provided on the evaluation board to allow designers to test their functionality.

  • Page 47: Suspend/Resume

    Suspend/Resume The ÉlanSC310 microcontroller evaluation board provides a hardware option to allow the user to toggle between the High Speed and Suspend modes. By pressing the Suspend/Resume button after the system has powered up, the system enters the Suspend mode (assuming the ACIN signal is low). By pressing the Suspend/ Resume button again, the system returns to High Speed mode.

  • Page 48: Micropower Off Mode

    MicroPower Off Mode This mode is the lowest power mode for the ÉlanSC310 microcontroller. When the system is initially powered by turning on the power supply and then pressing the MicroPower Off button, SW5, the system enters High Speed mode. The red power light indicates that the system is fully powered on.

  • Page 49: Using The Software

    Using the Software The ÉlanSC310 microcontroller evaluation board kit currently ships with four diskettes: the SystemSoft Evaluation diskette, the PhoneixPICO Evaluation diskette, the Datalight Software Evaluation Kit diskette, and the AMD Utilities diskette. SystemSoft Evaluation Diskette This diskette contains the evaluation version of SystemSoft’s BIOS ROM image programmed into the ROM on the evaluation board.

    EvalSet Serial and Parallel Port Setup Utility EVALSET.EXE has been provided to allow easy activation of the serial and parallel ports on the ÉlanSC310 microcontroller evaluation board. The BIOS on this board was designed to be generic, therefore these functions are not enabled by the BIOS on the evaluation board.

    Memory Management System (MMS) Viewer Utility This utility is part of the collateral for the ÉlanSC310 microcontroller. The ÉlanSC310 microcontroller is a highly integrated device with many subsystems. Many of these subsystems are unique to the ÉlanSC310. The purpose of the MMSVIEW utility is to provide the new ÉlanSC310 microcontroller user with the ability to explore the capabilities of the ÉlanSC310 MMS subsystem without having to invest much in the way of software development or chip register learning...

  • Page 61: Scope

    The fact that it may run on other customer platforms is purely coincidental NOTE: No support of any kind is provided for porting this utility to any platform other than the ÉlanSC310 microcontroller evaluation board revision 2.2 or later except by special agreement between AMD and the customer. Operating Instructions Command-Line Parameters MMSVIEW assumes that MMS page 4 (resides at D0000h when MMS page 0 is set up to reside at C0000h) is available for use.
  • Page 62 Initial State After MMSVIEW has been invoked from the DOS command line, data is displayed in a fashion similar to DOS debug. MMSA page 4 at D0000h is selected, and the device that is accessed is system RAM.

  • Page 63 Page Up The Page Up key displays data on the previous 16-Kbyte boundary. For example, if the current device data starting at offset 4100h is being displayed, and Page Up is pressed, the data from device offset 0100h is displayed. Page Down The Page Down key does the inverse of the Page Up key;...
  • Page 64 The d key selects which device the current MMS page points to. Pressing the d key causes the system to prompt for the new device. Enter a 0, 1, or 3 (0 = DOS ROM, 1 = system RAM, 3 = BIOS ROM), and press enter. Invalid input is not accepted.

  • Page 65: Restrictions On Use

    The n command allows the user to select the use of a new MMS page (0–7). This can be useful in avoiding system conflicts. The default page can be changed before entering the program using the command-line capability to set this option as described on page 3-13.
  • Page 66 2. The second element of compatibility is the use of the MMS windows on the customer platform. MMSVIEW assumes that MMS page 4 (resides at D0000h when MMS page 0 is set up to reside at C0000h) is available for use. This may conflict with drivers loaded on the evaluation board platform that require the use of MMS (ROMDOS, EMM386, etc.).

    Chapter 4 Developing Code This document is meant to aid the programmer who is developing BIOS code, Power Management code, etc. using the ÉlanSC310 microcontroller evaluation board. This evaluation board was designed to support a number of different system configurations (e.g., Full ISA Bus mode, Application ROM support, IDE drives, Floppy drive, etc.).

  • Page 70: Programmable General Purpose (Pgp) Pins

    Programmable General Purpose (PGP) Pins The ÉlanSC310 microcontroller has four Programmable General Purpose (PGP) pins which can be set up as inputs, outputs, address decodes, and address decodes that are gated with the I/O read or I/O write pulse. Index registers for the PGP pins are write only.

  • Page 71: Power Management Control (Pmc) Pins

    PGP1 This pin is used as an address decode for the IDE CS0. It should be programmed as an address decode for I/O addresses 1F0H–1F7H. Setting the ÉlanSC310 microcontroller’s Index 91h to xxxx11xxb programs PGP1 as an address decode. Setting ÉlanSC310 Index 9Ch to 3Eh sets the address range to 1F0h–1F7h. PGP1 must also be enabled as an output for the evaluation board.

    Evaluation Board’s I/O Map Because the ÉlanSC310 microcontroller and the evaluation board are so configurable, there is not one single I/O map that covers all cases. What is illustrated here is a typical memory map for the evaluation board configured in Full ISA mode with the ÉlanSC310 microcontroller internal serial port enabled as COM1, the Super I/O floppy drive controller enabled, an IDE hard drive, and the Super I/O serial port enabled as COM2.

  • Page 91: Board Layout Suggestions

    Appendix C Board Layout Suggestions The following suggestions concern the ÉlanSC310 microcontroller evaluation board layout strategy for the 32-kHz oscillator, the PLLs, and the power supplies. The goal is to minimize noise and noise coupling associated with the way the board is laid out.
  • Page 92 Phase-Locked Loops Board layout considerations for the four PLLs suggest the following precautions: • Keep the output traces for the four PLLs as short as possible and keep them as far away from each other (and other clocking signals) as possible. •...

  • Page 93: Schematics

    Appendix D Schematics The schematics beginning on page D-2 are the actual Orcad schematics used to build the ÉlanSC310 microcontroller evaluation board. These schematics are useful for understanding and modifying the evaluation board. Since the evaluation board incorporates many different possible configurations for the ÉlanSC310 microcontroller, these schematics are not a good place to start for actual ÉlanSC310 microcontroller-based designs.
