Detailed Description

Driver for the cc2538 Watchdog Timer.

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.

◆ 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.

Definition at line 85 of file watchdog.c.

Referenced by cfs_coffee_arch_erase(), platform_idle(), and platform_main_loop().

◆ watchdog_reboot()

void watchdog_reboot ( void  )

Keeps control until the WDT throws a reset signal.

Starts the WDT if not already started.

Definition at line 94 of file watchdog.c.
