8.3.2 Timer Input Capture Registers
When an edge has been detected and synchronized, the 16-bit free-running
counter value is transferred into the input capture register pair as a single 16-bit
parallel transfer. Timer counter value captures and timer counter incrementing
occur on opposite half-cycles of the phase two clock so that the count value is
stable whenever a capture occurs. The timer input capture (TICx) registers are not
affected by reset. Input capture values can be read from a pair of 8-bit read-only
registers. A read of the high-order byte of an input capture register pair inhibits a
new capture transfer for one bus cycle. If a double-byte read instruction, such as
LDD, is used to read the captured value, coherency is assured. When a new input
capture occurs immediately after a high-order byte read, transfer is delayed for an
additional cycle but the value is not lost.
