These
PTMOD1:PTMOD0 bits in the PTCON0 register. The
Free-Running mode produces edge-aligned PWM
generation. The Continuous Up/Down Count modes
produce center-aligned PWM generation. The Single-
Shot mode allows the PWM module to support pulse
control of certain Electronically Commutated Motors
(ECMs) and produces edge-aligned operation.
