TOI — Timer Overflow Interrupt Enable
Refer to 7 Main Timer.
RTII — Real-time Interrupt Enable
Refer to 7 Main Timer.
PAOVI — Pulse Accumulator Overflow Interrupt Enable
0 = PAOVF interrupts disabled
1 = Interrupt requested when PAOVF is set to one
PAII — Pulse Accumulator Input Edge Interrupt Enable
0 = PAIF interrupts disabled
1 = Interrupt requested when PAIF is set to one
Bits [3:2] — Not implemented
Always read zero
PR[1:0] — Timer Prescaler Select
Refer to 7 Main Timer.
NOTE
Bits in TMSK2 correspond bit for bit with flag bits 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
Refer to 7 Main Timer.
RTIF — Real-Time Interrupt Flag
Refer to 7 Main Timer.
PAOVF — Pulse Accumulator Overflow Flag
Set when PACNT changes from $FF to $00
PAIF — Pulse Accumulator Input Edge Flag
Set each time a selected active edge is detected on the PAI input line
Bits [3:0] — Not implemented
Always read zero
