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 PHASEx<15:0>: PWM Phase Shift Value or Independent Time Base Period for this PWM Generator bits
Note 1: If PWMCONx<ITB> = 0, the following applies based on the mode of operation:
• Complementary, Redundant and Push-Pull Output mode (IOCONx<PMOD> = 00, 01, or 10)
PHASEx<15:0> = Phase shift value for PWMxH and PWMxL outputs
• True Independent Output mode (IOCONx<PMOD> = 11) PHASEx<15:0> = Phase shift value for
PWMxL only
2: If PWMCONx<ITB> = 1, the following applies based on the mode of operation:
• Complementary, Redundant, and Push-Pull Output mode (IOCONx<PMOD> = 00, 01, or 10)
PHASEx<15:0> = Independent time base period value for PWMxH and PWMxL
• True Independent Output mode (IOCONx<PMOD> = 11) PHASEx<15:0> = Independent time base
period value for PWMxL only
• 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 Period - 0x0008.
