Register 11: Hibernation IO Configuration (HIBIO), offset 0x02C
This register is used to lock and unlock the external wake pin levels and enable the external RST
pin and/or GPIO pins, Port K[7:4], as valid external WAKE sources.

bit of
the HIBCTL register before issuing a read or write of this register. Writes to this register are
immediate.
