CHAPTER 8 8/16-BIT CAPTURE TIMER/COUNTER
●
16-bit mode
To operate timer 0 as the counter function in the 16 bit mode, the function must be set as shown in Figure
8.7-3 .
Figure 8.7-3 Setting of Counter Function in 16-bit Mode
Counter function operation in the 16-bit mode is the same as interval timer function operation in the 16-bit
mode, except that the external clock is used instead of the internal clock.
Figure 8.7-4 shows counter function operation in 16-bit mode.
