NOTES:
1. Vdet4 > Vdet3.
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 microcomputer operates with f(BCLK) ≤ 10MHz.
3. Vdet3r > Vdet3 is not guaranteed.
4. The voltage detection circuit is designed to use when VCC1 is set to 5V.
