•

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 16 MHz RC oscillator needed during power-up

phase and reset phase. When POWER_OK is low the associated modules are set into a safe state.
