NOTE:
Use this 8-bit register to enable or inhibit the timer input capture and output
compare interrupts.
OC1I–OC4I — Output Compare x Interrupt Enable Bits
I4/O5I — Input Capture 4/Output Compare 5 Interrupt Enable Bit
IC1I–IC3I — Input Capture x Interrupt Enable Bits
Bits in TMSK1 correspond bit for bit with flag bits in TFLG1. Bits in TMSK1 enable
the corresponding interrupt sources.
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 polled or interrupt driven system. Each bit of TFLG1 corresponds to a bit in
TMSK1 in the same position.
Clear flags by writing a 1 to the corresponding bit position(s).
OC1F–OC4F — Output Compare x Flag
I4/O5F — Input Capture 4/Output Compare 5 Flag
IC1F–IC3F — Input Capture x Flag
If the OCxI enable bit is set when the OCxF flag bit is set, a hardware interrupt
sequence is requested.
When I4/O5 in PACTL is 1, I4/O5I is the input capture 4 interrupt enable bit.
When I4/O5 in PACTL is 0, 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.
Set each time the counter matches output compare x value
Set by IC4 or OC5, depending on the function enabled by I4/O5 bit in PACTL
Set each time a selected active edge is detected on the ICx input line
