System Control
Register 30: Hibernation Peripheral Present (PPHIB), offset 0x314
The PPHIB register provides software information regarding the Hibernation module.
Important: This register should be used to determine if the Hibernation module is implemented on
this microcontroller. However, to support legacy software, the DC1 register is available.
A read of the DC1 register correctly identifies if the Hibernation module is present.

Description
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.
Hibernation Module Present
Value Description
