TOI — Timer Overflow Interrupt Enable
0 = TOF interrupts disabled
1 = Interrupt requested when TOF is set
RTII — Real-time Interrupt Enable
0 = RTIF interrupts disabled
1 = Interrupt requested when PAOVF is set
PAOVI — Pulse Accumulator Overflow Interrupt Enable
Refer to 8 Pulse Accumulator.
PAII — Pulse Accumulator Input Interrupt Enable
Refer to 8 Pulse Accumulator.
Bits [3:2] — Not implemented
Always read zero
PR[1:0] — Timer Prescaler Select
In normal modes, PR0 and PR1 can only be written once, and the write must occur within 64 cycles
after reset. The following table shows the prescaler selected with each combination of PR[1:0]. Refer
to Table 8 table for specific timing values.
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.
Clear flags by writing a one to the corresponding bit position(s).
TOF — Timer Overflow Flag
Set when TCNT changes from $FFFF to $0000
RTIF — Real-Time Interrupt Flag
Set periodically. Refer to RTR[1:0] in PACTL register.
PAOVF — Pulse Accumulator Overflow Flag
Refer to 8 Pulse Accumulator.
