16. General Overview of Timers
The MCU has two 8-bit timers with 8-bit prescalers, three 16-bit timers, and a timer with a 4-bit counter and an 8-bit
counter. The two 8-bit timers with 8-bit prescalers are timer RA and timer RB. These timers contain a reload register to
store the default value of the counter. The one 16-bit timer is timer RC, and the two 16-bit timers are timer RD, and
have input capture and output compare functions. The 4-bit and 8-bit counters are timer RE, and has an output compare
function. All the timers operate independently.
Table 16.1 lists Functional Comparison of Timers.
