12.3.17 Output Mask (FTMx_OUTMASK)
This register provides a mask for each FTM channel. The mask of a channel determines if
its output responds, that is, it is masked or not, when a match occurs. This feature is used
for BLDC control applications where the PWM signal is presented to an electric motor at
specific times to provide electronic commutation.
Any write to the OUTMASK register stores the value into a write buffer. The register is
updated with the value of its write buffer according to
