External PWM
The following can output PWM output waveforms when selected:
P0 to P4：PWM / General Purpose output is selected.
PG1 to PG6：PWM output is selected.
This control data bit select either GPO or external PWM output of Px/Gx pins(x=7 to 16).

External PWM output
The following can output PWM output waveforms when selected:
P0 to P4：PWM / General Purpose output is selected.
If any one of external PWM setting in EP1-EP16, PWMIN/S36 pin can be as input pin.
The relation of P0 to P4、Px/Gx(x = 1 to 6)、EP1 to EP16 is as follows
