Notes:
1. V_det0 indicates the voltage detection level of the voltage detection 0 circuit.
2. When using power-on reset, hold the external power V_CC1 at or below the valid voltage (0.1 V) during t_w(por), and
then turn it on.
t_w(por) is 30 s or more when -20 °C ≤ T_opr ≤ 85 °C, and 3000 s or more when -40 °C ≤ T_opr < -20 °C.

Notes:
1. The measurement condition is V_CC1 = 2.7 to 5.5 V and T_opr = 25°C.
2. Waiting time until the internal power supply generation circuit stabilizes when power is on.
