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 TMSK2 — Timer
interrupt mask register 2)
RTII — Real-time interrupt enable
1 = Real time interrupt requested when RTIF is set.
0 = Real time interrupts disabled.
PAOVI — Pulse accumulator overflow interrupt enable (refer to Pulse
accumulator)
PAII — Pulse accumulator input edge (refer to Pulse accumulator)
PR[1:0] — Timer prescaler select (refer to TMSK2 — Timer interrupt
mask register 2)
