APPENDIX Appendix A. I/O Port Address Map Each peripheral device in the system is assigned a set of I/O port addresses which also becomes the identity of the device. The following table lists the I/O port addresses used.
APPENDIX B. Interrupt Request Lines (IRQ) Peripheral devices use interrupt request lines to notify CPU for the service required. The following table shows the IRQ used by the devices on board.
APPENDIX C. Watchdog Timer Configuration The WDT is used to generate a variety of output signals after a user programmable count. The WDT is suitable for use in the prevention of system lock-up, such as when software becomes trapped in a deadlock. Under these sorts of circumstances, the timer will count to zero and the selected outputs will be driven. Under normal circumstance, the user will restart the WDT at regular intervals before the timer counts to zero.
