12.3
12.3.1
TCNT is incremented by input clock pulses (either internal or external).
Internal Clock: Three different internal clock signals (φ/8, φ/64, or φ/8192) divided from the
system clock (φ) can be selected, by setting bits CKS2 to CKS0 in TCR. Figure 12.2 shows the
count timing.
External Clock: Three incrementation methods can be selected by setting bits CKS2 to CKS0 in
TCR: at the rising edge, the falling edge, and both rising and falling edges.
Note that the external clock pulse width must be at least 1.5 states for incrementation at a single
edge, and at least 2.5 states for incrementation at both edges. The counter will not increment
correctly if the pulse width is less than these values.
Figure 12.3 shows the timing of incrementation at both edges of an external clock signal.
