Timing System
9.5.10 Timer Interrupt Flag Register 2
Technical Data
198
Address:
Bits in this register indicate when certain timer system events have
occurred. Coupled with the four high-order bits of TMSK2, the bits of
TFLG2 allow the timer subsystem to operate in either a polled or
interrupt driven system. Each bit of TFLG2 corresponds to a bit in
TMSK2 in the same position.
Clear flags by writing a 1 to the corresponding bit position(s).
TOF — Timer Overflow Interrupt Flag
RTIF — Real-Time (Periodic) Interrupt Flag
PAOVF — Pulse Accumulator Overflow Interrupt Flag
PAIF — Pulse Accumulator Input Edge Interrupt Flag
