TECHNICAL DATA
TFLG1 — Timer Interrupt Flag 1
TMSK2 — Timer Interrupt Mask 2
RESET:
RESET:
polled or interrupt driven system. Each bit of TFLG1 corresponds to a bit in TMSK1 in
the same position.
Clear flags by writing a one to the corresponding bit position(s).
Set each time the counter matches output compare x value
Set by IC4 or OC5, depending on the function enabled by I4/O5 bit in PACTL
Set each time a selected active edge is detected on the ICx input line
Use this 8-bit register to enable or inhibit timer overflow and real-time interrupts. The
timer prescaler control bits are included in this register.
Refer to 9.4 Real-Time Interrupt.
Refer to 9.6 Pulse Accumulator.
Refer to 9.6 Pulse Accumulator.
0 = TOF interrupts disabled
1 = Interrupt requested when TOF is set to one

Bit 7
TOI
Bits in TMSK2 correspond bit for bit with flag bits in TFLG2. Ones in
TMSK2 enable the corresponding interrupt sources.
