Real Time Clock (RTC)
27.1
The real time clock module (RTC) provides a time of day function as well as a calendar function. It also
provides a method to bring the MPC5125 from a power-down condition to a fully operational condition.
The RTC provides a time base as long as V
independently of the rest of the MPC5125 device. The RTC has its own internal 32.768 kHz oscillator
which is totally independent of the other MPC5125 clock domains. As long as V
can be used to cause the MPC5125 to exit any of the power-down modes, which include Doze, Nap, Sleep,
Deep Sleep, and Hibernation mode. The wakeup function can be initiated from the internal timer inside
the RTC module or from any of six external wakeup pins. An external pin, HIB_MODE, is associated with
the RTC and can be used to control the power supplies for the MPC5125. The RTC controls the
HIB_MODE pin in response to any RTC wakeup event, such as a transition on one of the six external
wakeup sources or a timeout event in the RTC module.
