AGREEMENT
REQUIRED
OLVL — Output Level
Value of output level is clocked into the output level register by the
next successful output compare and will appear on the TCMP pin.
1 = High output
0 = Low output
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
Reset clears this bit.
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
Reset clears this bit.
