2 to 65535
CD: Clock Divisor
This register has no effect if synchronous mode is selected with an external clock.
Note: In synchronous mode, the value programmed must be even to ensure a 50:50 mark:space ratio.
Note: Clock divisor bypass (CD = 1) must not be used when internal clock MCKI is selected (USCLKS = 0).
