50.6.14 Synchronization with PWM
The inputs TIOAx/TIOBx can be bypassed, and thus channel trigger/capture events can be directly driven by the
independent PWM module.
PWM comparator outputs (internal signals without dead-time insertion - OCx), respectively source of the PWMH/
L[2:0] outputs, are routed to the internal TC inputs. These specific TC inputs are multiplexed with TIOA/B input signal
to drive the internal trigger/capture events.
The selection is made in the Extended Mode register (TC_EMR) fields TRIGSRCA and TRIGSRCB (see “TC
Extended Mode Register”).
Each channel of the TC module can be synchronized by a dif
ferent PWM channel as described in the following figure.
