In pulse width modulation mode, the timer outputs pulse of desired width continuously (see Table 15.7).
The timer counter functions as either 16-bit pulse width modulator or 8-bit pulse width modulator. Figure
15.13 shows the TAiMR register (i=0 to 4) in pulse width modulation mode. Figures 15.14 and 15.15
show examples of how a 16-bit pulse width modulator operates and of how an 8-bit pulse width modulator
operates.

The value in the TAi register is indeterminate when read
• When the timer counter stops, the value written to the TAi register is also written to
• While counting, the value written to the TAi register is written to the reload register

Content of the reload register is reloaded on the rising edge of PWM pulse and count-

The timer is not affected by a trigger that is generated during counting.
