void watchdog_init ( void )

Initialisation function for the WDT.

Currently simply explicitly sets the WDT interval to max interval

< Watchdog Control

Definition at line 63 of file watchdog.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.
