8.7 Timer Status Register
The TSR is a read-only register containing three status flag bits.
ICF — Input Capture Flag
1 = Flag set when selected polarity edge is sensed by input capture
edge detector
0 = Flag cleared when TSR and input capture low register ($15) are
accessed
OCF — Output Compare Flag
1 = Flag set when output compare register contents match the free-
running counter contents
0 = Flag cleared when TSR and output compare low register ($17)
are accessed
TOF — Timer Overflow Flag
1 = Flag set when free-running counter transition from $FFFF to
$0000 occurs
0 = Flag cleared when TSR and counter low register ($19) are
accessed
Bits 0–4 — Not used
Always read 0
Accessing the timer status register satisfies the first condition required
to clear status bits. The remaining step is to access the register
corresponding to the status bit.
