FTMx_SYNC field descriptions
Field Description
31–8
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
7
SWSYNC
PWM Synchronization Software Trigger
Selects the software trigger as the PWM synchronization trigger. The software trigger happens when a 1 is
written to SWSYNC bit.
0 Software trigger is not selected.
1 Software trigger is selected.
6
TRIG2
PWM Synchronization Hardware Trigger 2
Enables hardware trigger 2 to the PWM synchronization. Hardware trigger 2 happens when a rising edge
is detected at the trigger 2 input signal.
0 Trigger is disabled.
1 Trigger is enabled.
5
TRIG1
PWM Synchronization Hardware Trigger 1
Enables hardware trigger 1 to the PWM synchronization. Hardware trigger 1 happens when a rising edge
is detected at the trigger 1 input signal.
0 Trigger is disabled.
1 Trigger is enabled.
4
TRIG0
PWM Synchronization Hardware Trigger 0
Enables hardware trigger 0 to the PWM synchronization. Hardware trigger 0 occurs when a rising edge is
detected at the trigger 0 input signal.
0 Trigger is disabled.
1 Trigger is enabled.
3
SYNCHOM
Output Mask Synchronization
Selects when the OUTMASK register is updated with the value of its buffer.
0 OUTMASK register is updated with the value of its buffer in all rising edges of the system clock.
1 OUTMASK register is updated with the value of its buffer only by the PWM synchronization.
2
REINIT
FTM Counter Reinitialization By Synchronization (FTM counter synchronization)
Determines if the FTM counter is reinitialized when the selected trigger for the synchronization is detected.
The REINIT bit configures the synchronization when SYNCMODE is zero.
0 FTM counter continues to count normally.
1 FTM counter is updated with its initial value when the selected trigger is detected.
