VPOR
TW(VPOR)
TW(VPOR-VDET)
Note: VPOR is the start voltage level of Vcc for the built-in power-on reset circuit to operate normally.
Keep VPOR to be lower than the Vcc voltage before rising of the Vcc power source to use the built-in power-on reset circuit.
Set the built-in low voltage detection circuit to be valid when the built-in power-on reset is used.

Note: VLVD is the start voltage level of Vcc for the built-in low voltage detection circuit to operate normally.
If the Vcc power source becomes lower than VLVD, first set the Vcc voltage to be lower than VPOR. Next, according to the electrical characteristics of
the power-on reset circuit, perform the rising of Vcc.
