13.1.4 Pulse Width Modulation (PWM) Mode
In PWM mode, the timer outputs pulses of a given width in succession. The counter functions as either
16-bit pulse width modulator or 8-bit pulse width modulator.
Table 13.5 lists the PWM Mode Specifications. Figure 13.12 shows Registers TA0MR to TA4MR in PWM
Mode. Figures 13.13 and 13.14 show an Example of 16-bit Pulse Width Modulator Operation and 8-bit
Pulse Width Modulator Operation.

• 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 n / fj
• Cycle time (2
• High level width n ✕ (m+1) / fj n : set value of the TAi register high-order address
• Cycle time (2
• The TAiS bit in the TABSR register is set to 1 (count starts)
• The TAiS bit = 1 and external trigger input from the TAiIN pin
• The TAiS bit = 1 and one of the following external triggers occurs
The TAiS bit is set to 0 (count stops)
I/O port or trigger input
Pulse output
An undefined value is read by reading the TAi register
• When not counting and until the 1st count source is input after counting start
• When counting (after 1st count source input)
Timer B2 overflow or underflow,
Timer Aj overflow or underflow,
Timer Ak overflow or underflow
Value written to the TAi register is written to both reload register and counter
Value written to the TAi register is written to only reload register
(Transferred to counter when reloaded next)
8
-1) ✕ (m+1) / fj m : set value of the TAi register low-order address
16
-1) / fj fixed fj : count source frequency (f1, f2, f8, f32, fC32)
n : set value of the TAi register
