If (FTMEN = 1), then the FTM counter is a free-running counter when (CPWMS = 0) and
(FTMxCNTINH:L = 0x0000) and (FTMxMODH:L = 0xFFFF).
11.4.20.4 Write to FTMxSC
If (FTMEN = 0), then a write to the FTMxSC register resets the write coherency mechanism of
FTMxMODH:L registers
(FTMxMODH:FTMxMODL)).
If (FTMEN = 1), then a write to the FTMxSC register does not reset the write coherency mechanism of
FTMxMODH:L registers.
11.4.20.5 Write to FTMxCnSC
If (FTMEN = 0), then a write to the FTMxCnSC register resets the write coherency mechanism of
FTMxCnVH:L registers
If (FTMEN = 1), then a write to the FTMxCnSC register does not reset the write coherency mechanism of
FTMxCnVH:L registers.
11.5
The FTM is reset whenever any MCU reset occurs
11.6
11.6.1
The timer overflow interrupt is generated when (TOIE = 1) and (TOF = 1).
11.6.2
The channel (n) interrupt is generated when (CHnIE = 1) and (CHnF = 1).
11.6.3
The fault interrupt is generated when (FAULTIE = 1) and (FAULTF = 1).
