Appendix Appendix Watchdog Programming Guide EC41812CLDNA provides a programmable watchdog timer (WDT) up to 255 levels and time by minute or second. Watchdog timer overtime event can be programmed to reset system or generate maskeble interrupts. The interrupt numbers used by the motherboard are 3, 4, 5, 7, 9, 10, 11. Please change the value of the corresponding IRQ number in PCIPnP of BIOS Setup interface into Reserved before using. The following describes WDT program in C language. The steps to program WDT are as follows: Ø Enter WDT programming mode Ø Setup WDT operating mode/enable WDT/disable WDT (1) Enter WDT Programming Mode #define INDEX_PORT 0x4E #define DATA_PORT 0x4F unsigned int tmp_reg; unsigned int pm_base; outportb(INDEX_PORT, 0x55); outportb(INDEX_PORT, 0x07); outportb(DATA_PORT, 0x0A); outportb(INDEX_PORT, 0x30); outportb(DATA_PORT, 0x01); outportb(INDEX_PORT, 0x60); 24 EC41812CLDNA ...
