void watchdog_init ( void )

Initialisation function for the WDT.

Currently simply explicitly sets the WDT interval to max interval

Definition at line 56 of file watchdog-arch.c.

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.
