PWM SINGLE and DUAL OUTPUT Modes
In PWM SINGLE OUTPUT mode, the timer outputs a PWM output signal through a
GPIO Port pin. In PWM DUAL OUTPUT mode, the timer outputs a PWM output signal
and also its complement through two GPIO port pins. The timer first counts up to the
16-bit PWM match value stored in the timer PWM high and low byte registers. When the
timer count value matches the PWM value, the timer output toggles. The timer continues
counting until it reaches the Reload value stored in the timer reload high and low byte reg-
isters. When it reaches the Reload value, the timer generates an interrupt. The count value
in the timer high and low byte registers is reset to
The timer output signal begins with value =
timer value matches the PWM value. The timer output signal returns to
timer reaches the Reload value and is reset to
In PWM DUAL OUTPUT mode, the timer also generates a second PWM output signal,
timer output complement (TOUT). A programmable deadband is configured (
to delay (0 to 128 system clock cycles) the Low to a High (inactive to active) output tran-
sitions on these two pins. This configuration ensures a time gap between the deassertion of
one PWM output to the assertion of its complement.
Observe the following steps to configure a timer for PWM SINGLE or DUAL OUTPUT
mode and initiate the PWM operation:
1. Write to the timer control registers to:
2. Write to the timer high and low byte registers to set the starting count value (typically
3. Write to the PWM high and low byte registers to set the PWM value.
4. Write to the timer reload high and low byte registers to set the Reload value (PWM
5. Enable the timer interrupt, if required and set the timer interrupt priority by writing to
6. Configure the associated GPIO port pin(s) for the timer output alternate function.
7. Write to the Timer Control 1 Register to enable the timer and initiate counting.
