uint32_t watch_get_backup_data(uint8_t reg)
Gets 32 bits of data from the RTC's BACKUP register.
Definition: watch_deepsleep.c:121
void watch_store_backup_data(uint32_t data, uint8_t reg)
Stores data in one of the RTC's backup registers, which retain their data in BACKUP mode.

void watch_enter_backup_mode(void)
Enters the SAM L22's lowest-power mode, BACKUP.
Definition: watch_deepsleep.c:188
void watch_enter_sleep_mode(void)
enters Sleep Mode by disabling all pins and peripherals except the RTC and the LCD.
