This chapter discusses the Sleep and Watchdog operations and their associated registers. For a complete table of the Sleep
and Watchdog registers, refer to the
isters in address order, refer to the
10.1
Device components that are involved in Sleep and Watchdog operation are the selected 32 kHz clock, the wakeup timer, the
Sleep bit in the CPU_SCR0 register, the sleep circuit (to sequence going into and coming out of sleep), the bandgap refresh
circuit (to periodically refresh the reference voltage during sleep), and the watchdog timer.
