Two successive commands are necessary. First, the counter/timers must be stopped. Sec-
ond, the status bits must be reset. These commands are required because it takes one
counter/timer clock interval for the initiated event to actually occur (see

You must program TC8L and TC8H to

When a subsequent edge (rising, falling, or both depending on CTR1 bits [5:4]) is detected
during counting, the current value of T8 is complemented and put into one of the capture
registers. If it is a positive edge, data is put into LO8; if it is a negative edge, data is put
Using the same instructions for stopping the counter/timers and setting the status bits is
not recommended.
