loop:
PMD and PLL.
The control flow and the program example are shown as follows.
The following is the program example from the start of PLL to beginning of the operation of PMD.
When shift to the low-power consumption modes other than IDLE1 and 2, switch the modes after stopping

PLL starts
; Set the lock-up count value to 2
; Start the operation of clock multiplier and lock-up counter
; Read PLLCR1
; PLLCR1<LUPFG>=1 ?
; Poll until finish of Lock-up
; supply a clock to PMD
; Enable PMD to operate by setting <PMD1EN> to "1"
; Set PMD to start operation
; Set <PWMEN> to "1" and enable PWM wave generation circuit to operate
