* Question
| What are the restrictions on stop mode? |
* Answer
| When all of the following four conditions are met, if the CMl0 bit of the CM1 register is set to “1” (stop mode), the microcontroller immediately generates a low voltage detection interrupt and returns from the stop mode.The VC27 bit in the VCR2 register is “1” (low voltage detection circuit is active).When the input voltage of the VCCl pin falls below Vdet4, it shifts to the stop mode, and when it rises above Vdet4, it returns from the stop mode.At this time, if the VCl3 bit is “0” (VCCI < Vdet4), the CM10 bit must be set to “1”. |
