should be increased to the recommended operating voltage range (Note) within 0.6ms from the detection
of the releasing voltage of the power-on reset circuit. If the supply voltage does not reach the range, the
TMPM380/M382 cannot operate properly.
The power-on reset circuit generates a reset when the power is turned on. When the supply voltage is
The power-on reset circuit consists of a reference voltage generation circuit, a comparator and a

When power supply voltage goes on, if the supply voltage is equal to or lower than the releasing voltage
When power supply voltage goes down, if the supply voltage is equal to or lower than the detecting
During the generation of power-on reset, the power-on counter circuit, the CPU and peripheral circuits

(Note） When the supply voltage rises, until the supply voltage (at DVDD5,DVDD5E and RVDD5 pins) reach the
recommended operating voltage range (4.5V through 5.5V) and 200μs passes by, the following condition should
be satisfied; Port L (PL0 and PL1) is opened or the input voltage is within 0.5 volts.
