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.

Disables the watchdog timer lock mechanism.
Prototype:
void
ROM_WatchdogUnlock(uint32_t ui32Base)

Parameters:
ui32Base is the base address of the watchdog timer module.
Description:
Enables write access to the watchdog timer configuration registers.
Returns:
None.
25.2.1.16 ROM_WatchdogValueGet
Gets the current watchdog timer value.
Prototype:
uint32_t
ROM_WatchdogValueGet(uint32_t ui32Base)
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].
