15.4.3.2 PWM Operating Modes

The PWM module supports a wide range of PWM modes for both motor control and power supply designs. The following PWM modes are supported:

• Independent Edge PWM mode (default)
• Variable Phase PWM mode
• Independent Edge PWM mode, Dual Output
• Center-Aligned PWM mode
• Double Update Center-Aligned PWM mode
• Dual Edge Center-Aligned PWM mode

The PWM modes are selected by setting the MODSEL[2:0] bits (PGxCON[2:0]). Some modes utilize multiple time base cycles to complete a single PWM cycle. Refer to Equation 15-2 for specifics on timing.
