In this mode, the timer outputs pulses of a given width in succession. (See Table 13.5) In this mode, the counter
functions as either a 16-bit pulse width modulator or an 8-bit pulse width modulator. Figure 13.11 shows the timer
Ai mode register in pulse width modulation mode. Figure 13.12 shows the example of how a 16-bit pulse width
modulator operates. Figure 13.13 shows the example of how an 8-bit pulse width modulator operates.

Bit symbol
f
• The timer counts down (operating as an 8-bit or a 16-bit pulse width modulator)
• The timer reloads a new count at a rising edge of PWM pulse and continues counting
• The timer is not affected by a trigger that occurs when counting
• High level width
• Cycle time
• High level width n (m+1) / fi n : values set to timer Ai register’s high-order address
• Cycle time (2
• External trigger is input
• The timer overflows
• The count start flag is set (= 1)
• The count start flag is reset (= 0)
