These control bit pairs are encoded to specify the action taken after a successful OCx
compare. OC5 functions only if the I4/O5 bit in the PACTL register is clear. Refer to
Table 9-3 for the coding.
Use this 8-bit register to enable or inhibit the timer input capture and output compare
interrupts.
If the OCxI enable bit is set when the OCxF flag bit is set, a hardware interrupt se-
quence is requested.
When I4/O5 in PACTL is one, I4/O5I is the input capture 4 interrupt enable bit. When
I4/O5 in PACTL is zero, I4/O5I is the output compare 5 interrupt enable bit.
If the ICxI enable bit is set when the ICxF flag bit is set, a hardware interrupt sequence
is requested.

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