The microcomputer has four 8-bit timers and one 16-bit timer. The four 8-bit timers are Timer 1, Timer X,
Timer Y, and Timer Z and each one has an 8-bit prescaler. The 16-bit timer is Timer C and has time
measurement function. All these timers function independently. The count source for each timer is the
operating clock that regulates the timing of timer operations such as counting and reloading.
Table 12.1 shows functional comparison.
