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. Figure 8-3 shows the logic of the input capture
function.
