M16C/64A Group 5. Electrical Characteristics
5.1.6 Voltage Detector and Power Supply Circuit Electrical Characteristics
Notes:
1. Select the voltage detection level with the VDSEL1 bit in the OFS1 address.
2. Necessary time until the voltage detector operates when setting to 1 again after setting the VC25 bit in the VCR2
register to 0.
3. Time from when passing the V
det0
until when a voltage monitor 0 reset is generated.
Notes:
1. Select the voltage detection level with bits VD1S0 to VD1S3 in the VD1LS register.
2. Necessary time until the voltage detector operates when setting to 1 again after setting the VC26 bit in the VCR2
register to 0.
3. Time from when passing the V
det1
until when a voltage monitor 1 reset is generated.
