Pulse width modulation (PWM) mode
IN
OUT
In this mode, the timer outputs pulses of a given width in succession. Table 1.43 shows the timer specification for Timer
in pulse width modulation mode. In this mode, the counter functions as either a 16-bit pulse width modulator or an 8-
bit pulse width modulator. Figure 1.85 shows the Timer Ai mode register in pulse width modulation mode. Figure 1.86
shows an example of how a 16-bit pulse width modulator operates. Figure 1.87 shows an example of how an 8-bit
pulse width modulator operates.
