Texas Instruments TM4C1294NCPDT User Manual

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.
Note: This register is in the system clock domain and does not require monitoring the WRC bit of
the HIBCTL register before issuing a read or write of this register. Writes to this register are
immediate.
Note: This register is in the core voltage domain and will not retain values over a hibernate cycle

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
