TOI — Timer Overflow Interrupt Enable
Refer to 10 Main Timer.
RTII — Real-Time Interrupt Enable
Refer to 10 Main Timer.
PAOVI — Pulse Accumulator Overflow Interrupt Enable
0 = Pulse accumulator overflow interrupt disabled
1 = Pulse accumulator overflow interrupt enabled
PAII — Pulse Accumulator Input Interrupt Enable
0 = Pulse accumulator input interrupt disabled
1 = Pulse accumulator input interrupt enabled if PAIF bit in TFLG2 register is set
Bits [3:2] — Not implemented
Always read zero
PR[1:0] — Timer Prescaler Select
Refer to 10 Main Timer.
NOTE
Control bits [7:4] in TMSK2 correspond bit for bit with flag bits [7:4] in TFLG2. Ones
in TMSK2 enable the corresponding interrupt sources.
