Counter
The key element in the programmable timer is a 16-bit, free-running
counter, or counter register, preceded by a prescaler that divides the
internal processor clock by four. The prescaler gives the timer a
resolution of 2s if the internal bus clock is 2MHz. The counter is
incremented during the low portion of the internal bus clock. Software
can read the counter at any time without affecting its value.
