In PWM mode, the timer outputs pulses of a given width in succession (see Table 12.1.4.1). The counter
functions as either 16-bit pulse width modulator or 8-bit pulse width modulator. Figure 12.1.4.1 shows
TAiMR register in pulse width modulation mode. Figures 12.1.4.2 and 12.1.4.3 show examples of how a
16-bit pulse width modulator operates and how an 8-bit pulse width modulator operates.

• Down-count (operating as an 8-bit or a 16-bit pulse width modulator)
• The timer reloads a new value at a rising edge of PWM pulse and continues counting
• The timer is not affected by a trigger that occurs during counting
• High level width
• Cycle time (2
• High level width n x (m+1) / fj n : set value of TAi register high-order address
• Cycle time
• TAiS bit in theTABSR register is set to “1” (= start counting)
• The TAiS bit is set to "1" and external trigger input from the TAi
• The TAiS bit is set to "1" and one of the following external triggers occurs
TAiS bit is set to “0” (= stop counting)
PWM pulse goes “L”
I/O port or trigger input
Pulse output
An indeterminate value is read by reading TAi register
