Function Documentation

watchdog_init()

void watchdog_init

(

void

)

Initialisation function for the WDT.

Currently simply explicitly sets the WDT interval to max interval

Definition at line 63 of file watchdog.c.

References SMWDTHROSC_WDCTL.

watchdog_periodic()

void watchdog_periodic

(

void

)

Writes the WDT clear sequence.

Due to how the SMWDTHROSC_WDCTL works, it is OK to simply write these bits rather than use RMW operations.
