the real time clock cannot generate a wakeup interrupt based on an alarm time to cause the MPC5125 to
exit the deep sleep mode. The deep sleep mode can only be exited in response to an external RTC wakeup
pin or when the actual time count register is greater than or equal to the target time register.
The second section of the RTC contains the target time register, actual time counter register, and the keep
alive register. This section of the RTC is powered by the V
V
When the CPU reads the value of the actual time count register, target time register or the keep alive
register, the value in the respective shadow register is actually fetched. The contents of the actual time
count register, target time register or the keep alive register are transferred to their respective shadow
registers on each cycle of the 1-second clock which increments the actual time count register.
For predictable operation, consecutive writes to the actual time count shadow register, the target time
shadow register or the keep alive shadow register must be separated by at least three clock periods of the
32.768 kHz RTC clock.
