bit 15-0 PHASEx<15:0>: PWM Phase Shift Value or Independent Time Base Period bits for the PWM Generator
Note 1: If PWMCONx<9> = 0 (Master Time Base mode), the following applies based on the mode of operation:
• Complementary, Redundant and Push-Pull PWM Output mode (IOCONx<11:10> = 00, 01 or 10)
PHASEx<15:0> = Phase shift value for PWMxH and PWMxL outputs.
• True Independent PWM Output mode (IOCONx<11:10> = 11) PHASEx<15:0> = Phase shift value
for PWMxH only.
• When PHASEx/SPHASEx register provides the phase shift with respect to the master time base,
the valid range of values is 0x0000 – Period.
2: If PWMCONx<9> = 1 (Independent Time Base mode), the following applies based on the mode of
operation:
• Complementary, Redundant and Push-Pull PWM Output mode (IOCONx<11:10> = 00, 01 or 10)
PHASEx<15:0> = Independent time base period value for PWMxH and PWMxL outputs.
• True Independent PWM Output mode (IOCONx<11:10> = 11) PHASEx<15:0> = Independent time
base period value for PWMxH only.
• When PHASEx/SPHASEx register provides the local period, the valid range of values
are0x0010–0xFFF8.
