TIMING SYSTEM
TECHNICAL DATA
9-11
polled or interrupt driven system. Each bit of TFLG1 corresponds to a bit in TMSK1 in
the same position.
Clear flags by writing a one to the corresponding bit position(s).
OC1F–OC5F — Output Compare x Flag
Set each time the counter matches output compare x value
I4/O5F — Input Capture 4/Output Compare 5 Flag
Set by IC4 or OC5, depending on the function enabled by I4/O5 bit in PACTL
IC1F–IC3F — Input Capture x Flag
Set each time a selected active edge is detected on the ICx input line
9.3.9 Timer Interrupt Mask 2 Register
Use this 8-bit register to enable or inhibit timer overflow and real-time interrupts. The
timer prescaler control bits are included in this register.
TOI — Timer Overflow Interrupt Enable
0 = TOF interrupts disabled
1 = Interrupt requested when TOF is set to one
RTII — Real-time Interrupt Enable
Refer to
9.4 Real-Time Interrupt
.
PAOVI — Pulse Accumulator Overflow Interrupt Enable
Refer to
9.6 Pulse Accumulator
.
PAII — Pulse Accumulator Input Edge Interrupt Enable
Refer to
9.6 Pulse Accumulator
.
NOTE
Bits in TMSK2 correspond bit for bit with flag bits in TFLG2. Ones in
TMSK2 enable the corresponding interrupt sources.
