Timing System
8.6.2 TFLG2 — Timer interrupt flag register 2
Technical Data
Timer interrupt flag 2 (TFLG2)
NOTE:
Bits of this register indicate the occurrence of timer system events.
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. Clear flags by writing a one to the corresponding bit position(s).
Bits in TFLG2 correspond bit for bit with flag bits in TMSK2. Ones in
TMSK2 enable the corresponding interrupt sources.
TOF — Timer overflow interrupt flag
RTIF — Real-time interrupt flag
PAOVF — Pulse accumulator overflow interrupt flag (refer to
accumulator)
PAIF — Pulse accumulator input edge interrupt flag (refer to
accumulator)
Bits [3:0] — Not implemented; always read zero
Freescale Semiconductor, Inc.
The RTIF status bit is automatically set to one at the end of every RTI
period.
Address bit 7
