Real Time Clock (RTC)
The assertion of the HIB_MODE pin does not affect the operation of the CPU. For instance, if the
HIB_MODE pin is not connected to anything (e.g., an external power regulator), then neither the assertion
of the HIB_MODE pin nor the mechanisms that cause the assertion of the HIB_MODE pin have any effect
on the operation of the MPC5125.
Point A Power is applied to the V
Point B The internal RTC_POR signal clears to a logic 0, which negates the internal reset and enables the
Point C The CPU writes 0x0000_0005 to the time target register and enables HIB_MODE function by
Point D The time target register value is greater than the actual time count register. In the diagrams,

reset signal to assert to a logic 0 at point A. When the internal reset signal is asserted, the actual
time count register is initialized to 0xFFFF_FFFE and the target time register is initialized to
0x0000_0000. Until these registers are modified with user software, the target time register is
always less than or equal to the actual time count register. Under this condition, the HIB_MODE
pin sets to a logic 1. If the HIB_MODE pin is connected to an external power regulator, the
regulator is turned on, thus supplying power to the MPC5125.
