counter that can be read but not written. There are two 10-bit match registers and compar-
ators. If the match register matches the counter, a pulse is output. Thus the timer can be
programmed to output a pulse at a predetermined count in the future. This pulse can be
used to clock the timer-synchronized parallel-port output registers as well as cause an
interrupt. Timer B is convenient for creating an event at a precise time in the future under
program control.
Figure 2-3 illustrates the Rabbit timers.
