Watchdog Timer
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_WATCHDOGTABLE is an array of pointers located at ROM_APITABLE[12].
ROM_WatchdogStallEnable is a function pointer located at ROM_WATCHDOGTABLE[13].
Parameters:
ui32Base is the base address of the watchdog timer module.
Description:
This function allows the watchdog timer to stop counting when the processor is stopped by the
debugger. By doing so, the watchdog is prevented from expiring (typically almost immediately
from a human time perspective) and resetting the system (if reset is enabled). The watchdog
will instead expired after the appropriate number of processor cycles have been executed while
debugging (or at the appropriate time after the processor has been restarted).
Returns:
None.
