OLVL — Output Level Bit
The 16-bit timer status register (TMRSR) is a read-only register
containing three status flag bits.
ICF – Input Capture Flag
OCF – Output Compare Flag
TOF – Timer Overflow Flag

Write:
Value of output level is clocked into output level register by the next
successful output compare and will appear on the TCMP pin.
1 = High output
0 = Low output
1 = Flag set when selected polarity edge is sensed by input capture
0 = Flag cleared when TMRSR and input capture low register ($15)
1 = Flag set when output compare register contents match the
0 = Flag cleared when TMRSR and output compare low register
1 = Flag set when free-running counter transition from $FFFF to
0 = Flag cleared when TMRSR and counter low register ($19) are
