14. Timers
The MCU has two 8-bit timers with 8-bit prescalers, and a 16-bit timer. The two 8-bit timers with 8-bit prescalers are
timer X and timer Z. These timers contain a reload register to store the default value of the counter. The 16-bit timer is
timer C, and has input capture and output compare functions. All the timers operate independently. The count source
for each timer is the operating clock that regulates the timing of timer operations such as counting and reloading.
Table 14.1 lists Functional Comparison of Timers.
