Under development Preliminary specification
Specifications in this manual are tentative and subject to change.
Notes:
1.
Select the voltage detection level with bits VDSEL0 and VDSEL1 in the OFS register.
2.
Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA25 bit in the VCA2
register to 0.
3.
Time until the voltage monitor 0 reset is generated after the voltage passes Vdet0.
Notes:
1.
Select the voltage detection level with bits VD1S0 to VD1S3 in the VD1LS register.
2.
Time until the voltage monitor 1 interrupt request is generated after the voltage passes Vdet1.
3.
Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA26 bit in the VCA2
register to 0.
