(12) W10 to W15, W20 to W25, W30 to W35 …… PWM data of the PWM output
These control data bits set the pulse width of the PWM output P1 to P4. However, when the PWM output function
isn’t used, these control data bits become invalid. In addition, when the external clock operating frequency is set
the fCK2=38[kHz] typ (EXF="1") in external clock operating mode (OC= "1") or when the serial data transfer is
the simple mode transfer, these control data bits become invalid.
