8.10 Power on reset (POR)
The power-on-reset circuit (POR) generates a power-on reset signal when power-on.
Power supply voltage is indicated as DVDD3(=AVDD3=RVDD3).
8.10.1 Configuration
Power-on-reset circuit consists of the reference voltage generation circuit, comparators, the LVD reset circuit and
the power-on counter.
This circuit compares a voltage divided by the ladder resistor with a reference voltage generated in the reference
voltage generation circuit in the comparator.
