14. Timers
The MCU contains two 8-bit timers with 8-bit prescaler, two 16-bit timers, and a timer with a 4-bit counter, and an 8-
bit counter. The two 8-bit timers with the 8-bit prescaler contain timer RA and timer RB. These timers contain a reload
register to memorize the default value of the counter. The 16-bit timer is timer RD which contains the input capture and
output compare. The 4 and 8-bit counters are timer RE which contains the output compare. All these timers operate
independently.
Table 14.1 lists Functional Comparison of Timers.
