PDCx<15:0>: PWM Generator # Duty Cycle Value bits
Note 1: In Independent PWM mode, the PDCx register controls the PWMxH duty cycle only. In Complementary,
Redundant and Push-Pull PWM modes, the PDCx register controls the duty cycle of both the PWMxH and
PWMxL. The smallest pulse width that can be generated on the PWM output corresponds to a value of
0x0008, while the maximum pulse width generated corresponds to a value of 0xFFEF.
2: As the duty cycle gets closer to 0% or 100% of the PWM period (0 ns-40 ns, depending on the mode of
operation), the PWM duty cycle resolution will degrade from 1 LSB to 3 LSB.

SDCx<15:0>: Secondary Duty Cycle for PWMxL Output Pin bits
Note 1: The SDCx register is used in Independent PWM mode only. When used in Independent PWM mode, the
SDCx register controls the PWMxL duty cycle. The smallest pulse width that can be generated on the
PWM output corresponds to a value of 0x0008, while the maximum pulse width generated corresponds to
a value of 0xFFEF.
2: As the duty cycle gets closer to 0% or 100% of the PWM period (0 ns-40 ns, depending on the mode of
operation), the PWM duty cycle resolution will degrade from 1 LSB to 3 LSB.
