The duty cycle of the PWMA channel SELn will be updated with the value stored in the DUTYn register when IMCHSEL is
written. If SELn points to a non-implemented channel, the write will be discarded.
The duty registers will be updated with the value stored in the DUTY3, DUTY2, DUTY1 and DUTY0 registers when the IMCH-
SEL register is written. Synchronization takes place immediately when an IMCHSEL 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. When only 8 bits duty cycle value are considered for updating, the four duty cycle values can be written to the
IMDUTY register once. This is equivalent to writing the 8 bits four duty cycle values to the four DUTY registers one by one while
the upper 4 bits remain unchanged.
