This register contains the real-time interrupt enable bit.
Note:
Bits in TMSK2 correspond bit for bit with flag bits in TFLG2. Ones in TMSK2 enable the
corresponding interrupt sources.
TOI — Timer overflow interrupt enable (refer to Section 8.1.4.9)
1 (set) – Timer overflow interrupt requested when TOF is set.
0 (clear) – TOF interrupts disabled.
RTII — Real-time interrupt enable
1 (set) – Real time interrupt requested when RTIF is set.
0 (clear) – Real time interrupts disabled.
8
PAOVI — Pulse accumulator overflow interrupt enable (refer to Section 8.1.8)
PAII — Pulse accumulator input edge (refer to Section 8.1.8)
Bits[3, 2] — Not implemented; always reads zero
PR[1, 0] — Timer prescaler select (refer to Section 8.1.4.9)
