FTMx_SYNC field descriptions (continued)
Field Description
0 External trigger 0 is not selected.
1 External trigger 0 is selected.
3
SYNCHOM
Output Mask Synchronization
Selects when the CHnOM bits in register OUTMASK are updated with the value of their write buffer.
0 CHnOM bits are updated with the value of the OUTMASK write buffer in all rising edges of the system
clock.
1 CHnOM bits are updated with the value of the OUTMASK write buffer only by the PWM
synchronization.
2
REINIT
FTM Counter Reinitialization by Synchronization (See “FTM Counter Synchronization”)
Determines if the FTM counter is reinitialized when the selected trigger for the synchronization is detected.
0 FTM counter continues to count normally.
1 FTM counter is updated with its initial value when the selected trigger is detected.
1
CNTMAX
Maximum Boundary Cycle Enable
Determines when the MOD, CNTIN, and CV registers are updated with their write buffer contents following
a PWM synchronization event. If CNTMAX is enabled, the registers are updated when the FTM counter
reaches its maximum value MOD.
0 The maximum boundary cycle is disabled.
1 The maximum boundary cycle is enabled.
0
CNTMIN
Minimum Boundary Cycle Enable
Determines when the MOD and CV registers are updated with their write buffer contents after a PWM
synchronization event. If CNTMIN is enabled, the registers are updated when the FTM counter reaches its
minimum value CNTIN.
0 The minimum boundary cycle is disabled.
1 The minimum boundary cycle is enabled.
