8.7 Timer Status Register
The timer status register (TSR) is a read-only register containing three
status flag bits.
ICF — Input Capture Flag Bit
1 = Flag set when selected polarity edge is sensed by input capture
edge detector
0=FlagclearedwhenTSRandinputcapturelowregister($15)are
accessed
OCF — Output Compare Flag Bit
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 Bit
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
