The microcomputer has eleven 16-bit timers. Five timers A and six timers B have different functions. Each
timer operates independently. The count source for each timer is the clock for timer operations including
counting and reloading, etc. Figures 14.1 and 14.2 show block diagrams of timer A and timer B configuration.
