Notes:

The measurement condition is Topr = −20 to 85°C/−40 to 85°C.

Select the voltage detection level with the VDSEL1 bit in the OFS1 address.

Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VC25 bit in the VCR2

Necessary time until the voltage monitor 0 reset generates after passing through Vdet0.

Notes:

The measurement condition is Topr = −20 to 85°C/−40 to 85°C.

Necessary time until the voltage monitor 1 interrupt request generates after passing through Vdet1.

Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VC26 bit in the VCR2

Notes:

The measurement condition is Topr = −20 to 85°C/−40 to 85°C.

Necessary time until the voltage monitor 2 interrupt request generates after passing through Vdet2
