26 PWM - Pulse-Width Modulation
The PWM module generates a Pulse-Width Modulated signal determined by the duty cycle, period, and resolution that are configured by the following registers:
- TxPR
- TxCON
- PWMxDC
- PWMxCON
Important: The corresponding TRIS bit must be cleared to
enable the PWM output on the PWMx pin.
Each PWM module uses the same timer source, Timer2, to control each module.
Figure 26-1 shows a simplified block diagram of PWM operation.
Figure 26-2 shows a typical waveform of the PWM signal.
For a step-by-step procedure on how to set up this module for PWM operation, refer to Setup for PWM Operation Using PWMx Output Pins.
