Section 10 8-Bit Timers
10.7.8
If compare matches A and B occur at the same time, the 8-bit timer operates according to the
relative priority of the output states set for compare match A and compare match B, as shown in
Table 10.5.
Table 10.5 Timer Output Priority Order
10.7.9
Switching internal clock sources may cause TCNT to increment, depending on the switchover
timing. Table 10.6 shows the relation between the time of the switchover (by writing to bits CKS1
and CKS0) and the operation of TCNT.
The TCNT input clock is generated from the internal clock source by detecting the rising edge of
the internal clock. If a switchover is made from a Low clock source to a High clock source, as in
case No. 3 in Table 10.6, the switchover will be regarded as a falling edge, a TCNT clock pulse
will be generated, and TCNT will be incremented.
TCNT may also be incremented when switching between internal and external clocks.
