6.3 Selectable Duty Cycle

The DC bits are used to modify the duty cycle of the output clock. A duty cycle of 0%, 25%, 50%, or 75% can be selected for all clock rates when the DIV value is not 0b000. When DIV=0b000 then the duty cycle defaults to 50% for all values of DC except 0b00 in which case the duty cycle is 0% (constant low output).

The duty cycle can be changed while the module is enabled. However, in order to prevent glitches on the output, the DC bits should only be changed when the module is disabled (EN = 0).

Important: The DC value at reset is 10. This makes the default duty cycle 50% and not 0%.
