This read/write bit enables interrupts caused by an active signal on
the TCAP pin or from CPF2 flag bit of the analog subsystem voltage
comparator 2. Reset clears the ICIE bit.
This read/write bit enables interrupts caused by an active match of the
output compare function. Reset clears the OCIE bit.
1 = Input capture interrupts enabled
0 = Input capture interrupts disabled
1 = Output compare interrupts enabled
0 = Output compare interrupts disabled
Enables input capture interrupts
Enables output compare interrupts
Enables timer overflow interrupts
Controls the active edge polarity of the TCAP signal
Controls the active level of the TCMP output
