10-15
TIMER/COUNTER UNIT
Figure 10-14 and Figure 10-15 shows writing a new count. If the counter receives a gate-trigger
after writing a new count but before the end of the current half-cycle, the count is loaded on the
next CLKINn pulse and counting continues from the new count (Figure 10-14). Otherwise, the
new count is loaded at the end of the current half-cycle (Figure 10-15).
