35.3.13 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 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 in its write buffer. The register is
updated with the value of its write buffer according to PWM synchronization.
Addresses: FTM0_OUTMASK is 4003_8000h base + 60h offset = 4003_8060h
FTM1_OUTMASK is 4003_9000h base + 60h offset = 4003_9060h
