Wait Mode
Table 1.10.3. Port status during wait mode
________
__________
When a WAIT instruction is executed, the BCLK stops and the microcomputer enters the wait mode. In this
mode, oscillation continues but the BCLK and watchdog timer stop. Writing “1” to the WAIT peripheral
function clock stop bit and executing a WAIT instruction stops the clock being supplied to the internal
peripheral functions, allowing power dissipation to be reduced. However, peripheral function clock f
does not stop so that the peripherals using f
running in low-speed or low power dissipation mode, do not enter WAIT mode with this bit set to “1”. Table
1.10.3 shows the status of the ports in wait mode.
Wait mode is cancelled by a hardware reset or an interrupt. If an interrupt is used to cancel wait mode, that
interrupt must first have been enabled, and the priority level of the interrupt which is not used to cancel must
have been changed to 0. If returning by an interrupt, the clock in which the WAIT instruction executed is set
to BCLK by the microcomputer, and the action is resumed from the interrupt routine. If only a hardware
reset or an NMI interrupt is used to cancel wait mode, change the priority level of all interrupt to 0,then shift
to wait mode.
