35.3.3 Status And Control (FTMx_SC)
SC contains the overflow status flag and control bits used to configure the interrupt
enable, FTM configuration, clock source, and prescaler factor. These controls relate to all
channels within this module.
Addresses: FTM0_SC is 4003_8000h base + 0h offset = 4003_8000h
FTM1_SC is 4003_9000h base + 0h offset = 4003_9000h

Reserved
This read-only field is reserved and always has the value zero.

TOF
Timer Overflow Flag
Set by hardware when the FTM counter passes the value in the MOD register. The TOF bit is cleared by
reading the SC register while TOF is set and then writing a 0 to TOF bit. Writing a 1 to TOF has no effect.
