14.4 PWM (Enhanced Mode)
The enhanced PWM function described in this section is
available for CCP modules ECCP1, ECCP2 and
ECCP3, with any differences between modules noted.
The enhanced PWM mode generates a Pulse-Width
Modulation (PWM) signal on up to four different output
pins with up to ten bits of resolution
Thank you for kind message milan,
But I don't want to use any gate due to cost increase and harmonics. And also I want to change both amplitude and frequency as changing PWM code.
