Section 9 8-Bit Timers
9.7.7
If an increment pulse occurs in the T
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
byte). If an increment pulse occurs in the T
