M16C/62P Group (M16C/62P, M16C/62PT) 5. Electrical Characteristics
Rev.2.41 Jan 10, 2006 Page 46 of 96
REJ03B0001-0241
NOTES:
1. V
det4 > 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. V
det3r > Vdet3 is not guaranteed.
4. The voltage detection circuit is designed to use when VCC1 is set to 5V.
NOTES:
1. When V
CC1 = 5V.
