REGISTER 16-12: PDCx: PWM GENERATOR DUTY CYCLE REGISTER
R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
PDCx<15:8>
bit 15 bit 8
R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
PDCx<7:0>
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-0 PDCx<15:0>: PWM Generator # Duty Cycle Value bits
Note: In Independent PWM mode, the PDCx register controls the PWMxH duty cycle only. In the Complementary,
Redundant and Push-Pull PWM modes, the PDCx register controls the duty cycle of both the PWMxH and
PWMxL.
REGISTER 16-13: SDCx: PWM SECONDARY DUTY CYCLE REGISTER
R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
SDCx<15:8>
bit 15 bit 8
R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
SDCx<7:0>
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-0 SDCx<15:0>: Secondary Duty Cycle bits for PWMxL Output Pin
Note: The SDCx register is used in Independent PWM mode only. When used in Independent PWM mode, the
SDCx register controls the PWMxL duty cycle.
