• WATCHDOG Timer
— Times out the system based on user-programmable
time-out period
— System power-down capability for power saving
— User-defined trigger events to restart WATCHDOG
— Optional routing of WATCHDOG output on IRQ
and/or SMI lines
• Strap Configuration
— Base Address (BADDR) strap to determine the base
address of the Index-Data register pair
— Test strap to force the device into test mode (re-
served for National Semiconductor use)
— X-Bus straps (XCNF2-0) define the functionality of
the X-Bus at reset
