Contention between TCNT Byte Write and Increment: If an increment pulse occurs in the T
or T
TCNT byte that was not written retains its previous value. See figure 10.63, which shows an
increment pulse occurring in the T
3
state of a TCNT byte write cycle, writing takes priority and TCNT is not incremented. The
