ICIE — Input Capture Interrupt Enable Bit
This read/write bit enables interrupts caused by an active signal on
the TCAP pin. Reset clears the ICIE bit.
1 = Input capture interrupts enabled
0 = Input capture interrupts disabled
OCIE — Output Compare Interrupt Enable Bit
This read/write bit enables interrupts caused by an active signal on
the TCMP pin. Reset clears the OCIE bit.
1 = Output compare interrupts enabled
0 = Output compare interrupts disabled
TOIE — Timer Overflow Interrupt Enable Bit
This read/write bit enables interrupts caused by a timer overflow.
Reset clears the TOIE bit.
1 = Timer overflow interrupts enabled
0 = Timer overflow interrupts disabled
IEDG — Input Edge Bit
The state of this read/write bit determines whether a positive or
negative transition on the TCAP pin triggers a transfer of the contents
of the timer register to the input capture register. Resets have no
effect on the IEDG bit.
1 = Positive edge (low to high transition) triggers input capture.
0 = Negative edge (high to low transition) triggers input capture.
OLVL — Output Level Bit
The state of this read/write bit determines whether a logic 1 or logic 0
appears on the TCMP pin when a successful output compare occurs.
Reset clears the OLVL bit.
1 = TCMP goes high on output compare.
0 = TCMP goes low on output compare.
