How long
does a
timer
take to
count?
First,
it’s
worth
mentioning
that
when a
timer is
in
interval
timer
mode (as
opposed
to event
counter
mode)
and
correctly
configured,
it will
increment
by 1
every
machine
cycle.
As you
will
recall
from the
previous
chapter,
a single
machine
cycle
consists
of 12
crystal
pulses.
Thus a
running
timer
will be
incremented:
11,059,000
/ 12 =
921,583
