Table 11.5 Switching of Internal Clocks and TCNT Operation (cont)

Timing of Switchover
by Means of CKS1
No. and CKS0 Bits
2 Clock switching from low

to high level∗
3 Clock switching from high

to low level∗
4 Clock switching from high
to high level
Notes: 1. Includes switching from low to stop, and from stop to low.
2. Includes switching from stop to high.
