R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared

Unimplemented: Read as ‘0’
IUE: Immediate Update Enable bit
1 = Updates to the active PxDC registers are immediate
0 = Updates to the active PxDC registers are synchronized to the PWM time base
OSYNC: Output Override Synchronization bit
1 = Output overrides via the PxOVDCON register are synchronized to the PWM time base
0 = Output overrides via the PxOVDCON register occur on next TCY boundary
UDIS: PWM Update Disable bit
1 = Updates from Duty Cycle and Period Buffer registers are disabled
0 = Updates from Duty Cycle and Period Buffer registers are enabled
