9. TIMERS
9. Timers
Eleven 16-bit timers, each capable of operating independently of the others, can be classified by function as either
timer A (five) and timer B (six). The count source for each timer acts as a clock, to control such timer operations as
counting, reloading, etc. Figures 9.1 and 9.2 show block diagrams of timer A and timer B configuration, respectively.
