7.6.3 Operation in PWM mode
The following explains operations of the pulse width modulator.
(1) 16-bit pulse width modulator
(2) 8-bit pulse width modulator
Each time a PWM pulse has been output for one period, the reload register’s contents are reloaded and
When the PWM mode is selected with the operating mode select bits, the TAi

The timer Ai interrupt request bit is set to “1” each time the PWM pulse level goes from “H” to “L.”
outputs a PWM pulse (Notes 1 and 2).
The interrupt request bit remains set to “1” until the interrupt request is accepted or until the interrupt
request bit is cleared to “0” by software.
the counter continues counting.
When the 16/8-bit PWM mode select bit is cleared to “0,” the counter operates as a 16-bit pulse width
modulator. Figures 7.6.5 and 7.6.6 show operation examples of the 16-bit pulse width modulator.
When the 16/8-bit PWM mode select bit is set to “1,” the counter is divided into 8-bit halves. Then,
the high-order 8 bits operate as an 8-bit pulse width modulator, and the low-order 8 bits operate as
an 8-bit prescaler. Figures 7.6.7 and 7.6.8 show operation examples of the 8-bit pulse width modulator.
