PIB Clock Detector Configuration Register
This register enables and configures the clock input presence detector for PIB. This detector is independent from the wakeup
source detector that triggers on any edge. This detector can establish whether a valid clock is present in active mode and is
coupled to the PIB_INTR.CLOCK_LOST interrupt.
