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.
