General Purpose Timers (GPT)
15.3.8
In this mode the I/O pin is an Output. The user can program Period and Width values to create an
adjustable, repeating output waveform on the I/O pin. A CPU interrupt can be generated at the beginning
of each PWM Period, at which time a new Width value can be loaded. The new Width value, which
represents ON time, is automatically applied at the beginning of the next period. There is no interrupt at
the beginning of the first PWM Period. This mode is suitable for PWM audio encoding.
The ON TIME for the PWM signal is programmed into the WIDTH field of the GPT_COUNTER register
in prescaled IP Bus Clocks. The Period of the PWM signal is programmed into the COUNT field of the
GPT Counter Input Register. The PRESCALE field of the GPT Counter Input Register applies to both the
COUNT value and the WIDTH Value. The ON TIME overlays the total period. That is, the WIDTH field
determines the total period of the PWM signal.
In the following example, the Prescale field equals 8, the Count field equals 6 and the Width field equals 2.

Set Count = 6

Pulse Width Modulation
It is the responsibility of the system software to set the Timer pin to the
desired state before setting up the PRESCALE and COUNT fields in the
GPT_COUNTER register.
