9.8.4
If compare match events A and B occur at the same time, the 8-bit timer operates in accordance
with the priorities for the output statuses set for compare match A and compare match B, as shown
in table 9.4.
Table 9.4
9.8.5
TCNT may increment erroneously when the internal clock is switched over. Table 9.5 shows the
relationship between the timing at which the internal clock is switched (by writing to the CKS1
and CKS0 bits) and the TCNT operation.
When the TCNT clock is generated from an internal clock, the falling edge of the internal clock
pulse is detected. If clock switching causes a change from high to low level, as shown in case 3 in
table 9.5, a TCNT clock pulse is generated on the assumption that the switchover is a falling edge.
This increments TCNT.
The erroneous incrementation can also happen when switching between internal and external
clocks.
