Real Time Clock (RTC)
27.1.1
The RTC module provides the following features:
The RTC is divided into two major sections. One section contains the target time shadow register, actual
time counter shadow register, keep alive shadow register and the time, date, alarm, and stopwatch registers.
This section is powered by the V
powered by the V
their contents.
To provide for the restoration of the date and time after all power is lost except for V
software needs to record a value of the actual time count register that corresponds with the contents of the
RTC current time register and current date register. These values must be stored in non-volatile memory.
Then, after power is restored, software must be used to deduce the current date and time based on the
current count of the actual time count register.
The time, date and stopwatch registers are updated by the 1-second clock that is derived from the RTC
32.768 kHz oscillator. When the MPC5125 enters the deep sleep mode, the contents of these registers are
maintained and updated as long as the V
by the 1-second clock derived from the RTC 32.768 kHz oscillator; however, when in the deep sleep mode,

Secure real time clock (SRTC_3_3V)
— Secure (not programmable) low-power timebase (actual time count register) that runs
— HIB_MODE (Hibernate) pin used to enable/disable external power regulator
— Programmable timeout and six external wakeup sources, for exiting HIB_MODE
— Wakeup source bits and four additional bits in RTC keep alive register can be used as an 8-bit
— Loss of power bit, TAMP
Normal RTC functions under software control
— Minute countdown timer—provides 256-minute capability, slightly over 4 hours
— Programmable alarm—operates on time of day only, not related to calendar
— Periodic interrupts for:
