External Wake-Up from Hibernation
The following steps are needed to use the Hibernation module with the external WAKE pin as the
wake-up source for the microcontroller:

Register Map
Table 7-1 on page 115 lists the Hibernation registers. All addresses given are relative to the Hibernation
Module base address at 0x400F.C000.
Note:
Set the RTC Match Wake-Up and start the hibernation sequence by writing 0x0000.004F to the
HIBCTL register at offset 0x010.
Write any data to be retained during power cut to the HIBDATA register at offsets 0x030-0x12C.
Enable the external wake and start the hibernation sequence by writing 0x0000.0056 to the
HIBCTL register at offset 0x010.
Write the required RTC match value to the HIBRTCMn registers at offset 0x004 or 0x008.
Write the required RTC load value to the HIBRTCLD register at offset 0x00C.
Write any data to be retained during power cut to the HIBDATA register at offsets 0x030-0x12C.
Set the RTC Match/External Wake-Up and start the hibernation sequence by writing 0x0000.005F
to the HIBCTL register at offset 0x010.
HIBRTCC, HIBRTCM0, HIBRTCM1, HIBRTCLD, HIBRTCT, and HIBDATA are on the
Hibernation module clock domain and require a delay of t
accesses. See “Register Access Timing” on page 111.
