The microcomputer has three 8-bit timers and one 16-bit timer. The three 8-bit timers are Timer X, Timer Y,
and Timer Z and each one has an 8-bit prescaler. The 16-bit timer is Timer C and has input capture and
output compare. 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 lists functional comparison.
