Contention between 8TCNT Byte Write and Increment in 16-Bit Count Mode
(Cascaded Connection)
If an increment pulse occurs in the T
or T
state of an 8TCNT byte write cycle in 16-bit count

mode, the counter write takes priority and the byte data for which the write was performed is not
incremented. The byte data for which a write was not performed is incremented. Figure 9.24
shows the timing when an increment pulse occurs in the T
state of a byte write to 8TCNT (upper
2
byte). If an increment pulse occurs in the T
state, on the other hand, the increment takes priority.
