If the OCxF flag bit is set while the OCxI enable bit is set, a hardware interrupt sequence is requested.
When I4/O5 in PACTL is one, I4/O5I is the input capture 4 interrupt bit. When I4/O5 in PACTL is zero,
I4/O5I is the output compare 5 interrupt control bit.
If the ICxF flag bit is set while the ICxI enable bit is set, a hardware interrupt sequence is requested.
Clear flags by writing a one to the corresponding bit position(s).
Set each time the counter matches output compare x value
Set by IC4 or OC5, depending on which function was enabled by I4/O5 of PACTL
Set each time a selected active edge is detected on the ICx input line

Control bits in TMSK1 correspond bit for bit with flag bits in TFLG1. Ones in TMSK1
enable the corresponding interrupt sources.
