Stabilize supply voltage to meet the power supply standard when using the PLL frequency synthesizer.

Do not stop an external clock running if the main clock is selected as the CPU clock while the external
clock is applied to the X
Do not set the CM05 bit in the CM0 register to "1" (main clock stopped) while the external clock input is
used for the CPU clock.
Set the PM12 bit in the PM1 register to "0" (no wait state) when changing the MCD4 to MCD0 bit settings
in the MCD register.
Stabilize the main clock, sub clock or PLL clock to switch the CPU clock source to each clock.

G
When entering wait mode while the CM02 bit in the CM0 register is set to "1" (peripheral function stop
in wait mode), set the MCD4 to MCD0 bits in the MCD register to maintain 10-MHz CPU clock fre-
quency or less.
When entering wait mode, the instruction queue reads ahead to instructions following the WAIT in-
struction, and the program stops. Write at least 4 NOP instructions after the WAIT instruction.
