15.4.3.2.6 Double Update Center-Aligned PWM Mode

Double Update Center-Aligned PWM mode works identically to Center-Aligned PWM mode, except that two interrupts and two data buffer updates occur per PWM cycle. This mode is useful when the user wants to decrease the latency of a control loop response. Note that this will eliminate the symmetrical nature of the Center-Aligned PWM mode pulse, since the rising edge and falling edge of the pulse can be controlled independently. Double Update Center-Aligned PWM mode is selected when MODSEL[2:0] (PGxCON[2:0]) = 101. Figure 15-11 shows the relationship between the control SFRs and the output waveform.
