Revision (See Manual for Details)
Figure amended
Description amended
If an increment pulse occurs in the T
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
8TCNT (upper byte). If an increment pulse occurs in the T
state, on the other hand, the increment takes priority.
