CHAPTER 8 8/16-BIT CAPTURE TIMER/COUNTER
● 16-bit mode
To operate timer 0 as the interval timer function in the 16-bit mode, the function must be set as shown in
Figure 8.6-4 .

In the 16-bit mode, timers are controlled by the timer 0 control register (TCR0), but the timer 1 control
register (TCR1) must be initialized. The values to be set in the data register are the higher 8 bits of TDR1
and the lower 8 bits of TDR0 (16 bits in total). The values are compared with the 16-bit counter value. The
16 bits of the counter are cleared at the same time. Other operations in the 16-bit mode are the same as
timer 0 operation in the 8-bit mode.
