8.1.1 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 2.2 microseconds if the
internal bus clock is 1.8MHz. 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.
The double-byte, free-running counter can be read from either of two locations,
$19-$1A (counter register) or $1B-$1C (counter alternate register). A read from
only the least signicant byte (LSB) of the free-running counter ($1A, $1C)
receives the count value at the time of the read. If a read of the free-running
