Device-specific information
For MPC5606BK, the device specific information is the following:
•
SXOSC, FIRC, and SIRC clocks are provided as counter clocks for the RTC. Default clock on reset
is SIRC divided by 4.
•
The RTC will be reset on destructive reset, with the exception of software watchdog reset.
•
The RTC provides a configurable divider by 512 to be optionally used when FIRC source is
selected.

Modes of operation
13.4.1
Functional mode
There are two functional modes of operation for the RTC: normal operation and low power mode. In
normal operation, all RTC registers can read or written and the input isolation is disabled. The RTC/API
