POWER ON RESET FOR 3.3V SUPPLY
The power-on-reset(POR) generates a reset pulse to ensure that the core processing circuits are in a defined state when the power is ramping up or ramping down. The POR detects the safe supply thresholds and protects the core circuits in case of supply regulation problems.
The inbuilt timer in POR generates a delays in the power-up to keep the chip in desired configuration. Once the supply is in safe limits and defined delay is provided, the POR generates a negative pulse to reset the core circuits. Thus, when reset is released the core is always in a defined state.
