CSAE (Core to SIB Access Enabled).
0: Core access to the SIB bus is disabled (default)
1: Core access to the SIB bus is enabled. The device to be accessed is selected by the SIB Device Select
address and enabled device specified in CRSMAE register. A write of 0 to this bit is ignored. This bit
is cleared when the read operation is completed, indicating that the data is ready in IHD register.
CSWR (Core Write to SIB). The bit is set by a write operation to IHD register. It is cleared when the
write to the SIB is completed.
RTC module. This bit is cleared by the hardware once the reset pulse is completed. Writing 0 to this
