1. Limitations on stop mode
With the VC13 bit of the VCR1 register equal to “1” (V
equal to “1” (V
detection interrupt enabled), if the CM10 bit of the CM1 register is set to “1” (stop mode), a V
detection interrupt is immediately generated, causing the microcomputer to get out of stop mode.
In systems where the microcomputer enters the stop mode when the input voltage in the V
