Timer/PWM (TPM)
10.6.4
For channels that are configured for PWM operation, there are two possibilities:
The flag is cleared by the 2-step sequence described in
10.7
The TPM includes:
Each timer channel has:
Refer to the direct-page register summary in the
assignments for all TPM registers. This section refers to registers and control bits only by their names. A
Freescale-provided equate or header file is used to translate these names into the appropriate absolute
addresses.

When the channel is configured for edge-aligned PWM, the channel flag is set when the timer
counter matches the channel value register that marks the end of the active duty cycle period.
When the channel is configured for center-aligned PWM, the timer count matches the channel
value register twice during each PWM cycle. In this CPWM case, the channel flag is set at the start
and at the end of the active duty cycle, which are the times when the timer counter matches the
channel value register.
