If the bit n in SET is one, the duty cycle of PWMA channel n will be updated with the value written to ISDUTY.
If more than one ISCHSET register is present, ISCHSET0 controls channels 31 to 0 and ISCHSET1 controls channels 63 to 32.
The duty registers will be updated with the value stored in the ISDUTY register when any ISCHSETm register is written. Syn-
chronization takes place immediately when an ISCHSET register is written. The duty cycle registers will, however, not be
updated until the synchronization is completed and the timebase counter reaches its top value in order to avoid glitches.
