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.
