FTMx_MODE field descriptions (continued)
Field Description
0 TPM compatibility. Free running counter and synchronization compatible with TPM.
1 Free running counter and synchronization are different from TPM behavior.
39.3.11 Synchronization (FTMx_SYNC)
This register configures the PWM synchronization.
A synchronization event can perform the synchronized update of MOD, CV, and
OUTMASK registers with the value of their write buffer and the FTM counter
initialization.
NOTE
The software trigger, SWSYNC bit, and hardware triggers
TRIG0, TRIG1, and TRIG2 bits have a potential conflict if
used together when SYNCMODE = 0. Use only hardware or
software triggers but not both at the same time, otherwise
unpredictable behavior is likely to happen.
The selection of the loading point, CNTMAX and CNTMIN
bits, is intended to provide the update of MOD, CNTIN, and
CnV registers across all enabled channels simultaneously. The
use of the loading point selection together with SYNCMODE =
0 and hardware trigger selection, TRIG0, TRIG1, or TRIG2
bits, is likely to result in unpredictable behavior.
The synchronization event selection also depends on the
PWMSYNC (MODE register) and SYNCMODE (SYNCONF
register) bits. See PWM synchronization.
