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
the following table 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 this register indicate when timer system events have occurred. Coupled with the
bits of TMSK1, the bits of TFLG1 allow the timer subsystem to operate in either a

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