Functional Description
The following figure shows the FTM counter overflow in up counting. In this case, when
the FTM counter changes from MOD to CNTIN, TOF and TOFDIR bits are set. TOF bit
indicates the FTM counter overflow occurred. TOFDIR indicates the counting was up
when the FTM counter overflow occurred.
The following figure shows the FTM counter overflow in down counting. In this case,
when the FTM counter changes from CNTIN to MOD, TOF bit is set and TOFDIR bit is
cleared. TOF bit indicates the FTM counter overflow occurred. TOFDIR indicates the
counting was down when the FTM counter overflow occurred.
