Power up/down sequencing
To prevent an overstress event or a malfunction within and outside the device, the MPC5604P implements the following
sequence to ensure each module is started only when all conditions for switching it ON are available:
A POWER_ON module working on voltage regulator supply controls the correct start-up of the regulator. This is a
key module ensuring safe configuration for all voltage regulator functionality when supply is below 1.5V. Associated
POWER_ON (or POR) signal is active low.
Several low voltage detectors, working on voltage regulator supply monitor the voltage of the critical modules (voltage
regulator, I/Os, flash memory and low voltage domain). LVDs are gated low when POWER_ON is active.
A POWER_OK signal is generated when all critical supplies monitored by the LVD are available. This signal is active
high and released to all modules including I/Os, flash memory and RC16 oscillator needed during power-up phase and
reset phase. When POWER_OK is low the associated module are set into a safe state.
