8.5.10 TFLG2 — Timer interrupt flag register 2
MC68HC11P2 — Rev 1.0
Timer interrupt flag 2 (TFLG2)
NOTE:
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. 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 (periodic) interrupt flag (refer to
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.
These bits are used to select the prescaler divide-by ratio. In normal
modes, PR[1:0] can only be written once, and the write must be within
64 cycles after reset. See
