8.4.2 Timer Status Register
The timer status register (TSR), shown in Figure 8-3, contains flags to
signal these conditions:
An active signal on the TCAP pin, transferring the contents of the
timer registers to the input capture registers
A match between the 16-bit counter and the output compare
registers, transferring the OLVL bit to the TCMP pin
A timer roll over from $FFFF to $0000
ICF — Input Capture Flag
The ICF bit is set automatically when an edge of the selected polarity
occurs on the TCAP pin. Clear the ICF bit by reading the timer status
register with ICF set and then reading the low byte ($0015) of the
input capture registers. Resets have no effect on ICF.
OCF — Output Compare Flag
The OCF bit is set automatically when the value of the timer registers
matches the contents of the output compare registers. Clear the OCF
bit by reading the timer status register with OCF set and then reading
the low byte ($0017) of the output compare registers. Resets have no
effect on OCF.
TOF — Timer Overflow Flag
The TOF bit is set automatically when the 16-bit counter rolls over
from $FFFF to $0000. Clear the TOF bit by reading the timer status
register with TOF set, and then reading the low byte ($0019) of the
timer registers. Resets have no effect on TOF.
