TIMING SYSTEM
TECHNICAL DATA
9-13
The clock source for the RTI function is a free-running clock that cannot be stopped or
interrupted except by reset. This clock causes the time between successive RTI time-
outs to be a constant that is independent of the software latencies associated with flag
clearing and service. For this reason, an RTI period starts from the previous time-out,
not from when RTIF is cleared.
Every time-out causes the RTIF bit in TFLG2 to be set, and if RTII is set, an interrupt
request is generated. After reset, one entire real-time interrupt period elapses before
the RTIF flag is set for the first time. Refer to the TMSK2, TFLG2, and PACTL regis-
ters.
9.4.1 Timer Interrupt Mask 2 Register
This register contains the real-time interrupt enable bits.
TOI — Timer Overflow Interrupt Enable
Refer to 9.3 Output Compare.
RTII — Real-time Interrupt Enable
0 = RTIF interrupts disabled
1 = Interrupt requested when RTIF is set to one
PAOVI — Pulse Accumulator Overflow Interrupt Enable
Refer to 9.6 Pulse Accumulator.
PAII — Pulse Accumulator Input Edge
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.
9.4.1 Timer Interrupt Flag 2 Register
Bits of this register indicate the occurrence of timer system events. Coupled with the
four high-order bits of TMSK2, the bits of TFLG2 allow the timer subsystem to operate
in either a polled or interrupt driven system. Each bit of TFLG2 corresponds to a bit in
TMSK2 in the same position.
