34 | * Interface for Watchdog Timer (WDT) controller. |
---|
35 | * |
---|
36 | * \section Usage |
---|
37 | * -# Enable watchdog with given mode using \ref WDT_Enable(). |
---|
38 | * -# Disable watchdog using \ref WDT_Disable() |
---|
39 | * -# Restart the watchdog using \ref WDT_Restart(). |
---|
40 | * -# Get watchdog status using \ref WDT_GetStatus(). |
---|
41 | * -# Calculate watchdog period value using \ref WDT_GetPeriod(). |
