8.9 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).

8.9.1 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.

Figure 8.3 Power-on-reset circuit

For details of LVDRCR in LVD reset circuit, refer to Section "Low Voltage Detection Circuit (LVD)".
