Field Function
FLTPS The bits FLTPS selects the clock prescaler used in the FTM filters:
• channel input filters
• fault inputs filters
Writing to the bits FLTPS has immediate effect.
0000b - Divide by 1
0001b - Divide by 2
0010b - Divide by 3
0011b - Divide by 4
0100b - Divide by 5
0101b - Divide by 6
0110b - Divide by 7
0111b - Divide by 8
1000b - Divide by 9
1001b - Divide by 10
1010b - Divide by 11
1011b - Divide by 12
1100b - Divide by 13
1101b - Divide by 14
1110b - Divide by 15
1111b - Divide by 16
23-16
PWMENn
Channel n PWM enable bit
This bit enables the PWM channel output. This bit should be set to 0 (output disabled) when an input
mode is used.
0b - Channel output port is disabled.
1b - Channel output port is enabled.

9
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.
If another FTM overflow occurs between the read and write operations, the write operation has no effect;
therefore, TOF remains set indicating an overflow has occurred. In this case, a TOF interrupt request is
not lost due to the clearing sequence for a previous TOF.
0b - FTM counter has not overflowed.
1b - FTM counter has overflowed.
8
TOIE
Timer Overflow Interrupt Enable
Enables FTM overflow interrupts.
0b - Disable TOF interrupts. Use software polling.
1b - Enable TOF interrupts. An interrupt is generated when TOF equals one.
7
RF
Reload Flag
The RF bit is set at each selected reload point. See Reload Points .
The RF bit is cleared by reading the SC register while RF is set and then writing a 0 to RF bit. Writing 1 to
RF has no effect. If another selected reload point happens between the read and write operations, the
write operation has no effect; therefore, RF remains set.
0b - A selected reload point did not happen.
1b - A selected reload point happened.
6
RIE
Reload Point Interrupt Enable
Enables the reload point interrupt.
