set or clear. The input capture register always contains the free-running counter
value that corresponds to the most recent input capture.
After a read of the input capture register ($14) MSB, the counter transfer is inhibited
until the LSB ($15) is also read. This characteristic causes the time used in the
input capture software routine and its interaction with the main program to
determine the minimum pulse period.
A read of the input capture register LSB ($15) does not inhibit the free-running
counter transfer since they occur on opposite edges of the internal bus clock.
