9.6.2 Timer Interrupt Flag Register 2
M68HC11E Family — Rev. 3.2
MOTOROLA
Address:
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. 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 Interrupt Flag
PAOVF — Pulse Accumulator Overflow Interrupt Flag
PAIF — Pulse Accumulator Input Edge Interrupt Flag
Bits [3:0] — Unimplemented
Reset:
Read:
Write:
Set when TCNT changes from $FFFF to $0000
The RTIF status bit is automatically set to 1 at the end of every RTI
period. To clear RTIF, write a byte to TFLG2 with bit 6 set.
