* Question
| What are the restrictions on the waiting mode? |
* Answer
| When all of the following five conditions are met, if the WAIT instruction is executed, the microcontroller immediately generates a low voltage detection interrupt, returning from the wait mode.The CM02 bit in the CM0 register is “1” (stops the peripheral function clock).The VC27 bit in the VCR2 register is “1” (low voltage detection circuit is active).When the input voltage of the VCCl pin rises above Vdet4 (the VCl3 bit of the VCR1 register is “1”). When the input voltage of the VCCl pin falls below Vdet4, it shifts to the wait mode. When it rises above Vdet4, it returns from the wait mode. |
