5.5.2. Limitations on Stop Mode
When all the conditions below are met, the low voltage detection interrupt is generated and the MCU exits
stop mode as soon as the CM10 bit in the CM1 register is set to 1 (all clocks stopped).
• the VC27 bit in the VCR2 register is set to 1 (low voltage detection circuit enabled)
• the D40 bit in the D4INT register is set to 1 (low voltage detection interrupt enabled)
• the D41 bit in the D4INT register is set to 1 (low voltage detection interrupt is used to exit stop mode)
• the voltage applied to the V
Set the CM10 bit to 1 when the VC13 bit is set to set to 0 (V
stop mode when voltage applied to the V
voltage applied rises to Vdet4 or above.
5.5.3. Limitations on WAIT Instruction
When all the conditions below are met, the low voltage detection interrupt is generated and the MCU exits
wait mode as soon as WAIT instruction is executed.
• the CM02 bit in the CM0 register is set to 1 (stop peripheral function clock)
• the VC27 bit in the VCR2 register is set to 1 (low voltage detection circuit enabled)
• the D40 bit in the D4INT register is set to 1 (low voltage detection interrupt enabled)
• the D41 bit in the D4INT register is set to 1 (low voltage detection interrupt is used to exit wait mode)
• the voltage applied to the V
Execute the WAIT instruction when the VC13 bit is set to set to 0 (V
to enter wait mode when voltage applied to the V
the voltage applied rises to Vdet4 or above.
