COUNT
Description
This read-only field is reserved and always has the value zero.
Counter value
39.3.5 Modulo (FTMx_MOD)
The Modulo register contains the modulo value for the FTM counter. After the FTM
counter reaches the modulo value, the overflow flag (TOF) becomes set at the next clock,
and the next value of FTM counter depends on the selected counting method (Counter).
Writing to the MOD register latches the value into a buffer. The MOD register is updated
with the value of its write buffer according to Registers Updated from Write Buffers.
If FTMEN = 0, this write coherency mechanism may be manually reset by writing to the
SC register (whether BDM is active or not).
It is recommended to initialize the FTM counter (write to CNT) before writing to the
MOD register to avoid confusion about when the first counter overflow will occur.
Addresses: FTM0_MOD is 4003_8000h base + 8h offset = 4003_8008h
FTM1_MOD is 4003_9000h base + 8h offset = 4003_9008h
FTM2_MOD is 400B_8000h base + 8h offset = 400B_8008h
