Note 1: Vdet4 > Vdet3
Note 2: Where reset level detection voltage is less than 2.7 V, if the supply power voltage is greater than the reset level detection voltage, the
operation at f(BCLK) ≤ 10MHz is guaranteed.
Note 3: Vdet3r > Vdet3 is not guaranteed.
Note 4: The low voltage detection circuit is designed to use when VCC is set to 5V.
