CHAPTER 7 16-BIT FREE-RUNNING TIMER AND 16-BIT RELOAD TIMER
■ Output Pin Function
The TOT (0-3) output pin provides a toggle output that is inverted by an underflow in reload mode and a
pulse output that indicates that counting is in progress in one-shot mode. The output polarity can be set
using the OUTL bit of the register. If OUTL=0, toggle output is "0" for the initial value and the one-shot
pulse output is "1" while the count operation is in progress. If OUTL=1, the output waveform is reversed.
Note:
The MB91F353A/351A/352A/353A do not have the TOT (0-3) output function.
Figure 7.2-4 and Figure 7.2-5 show the timing charts for output pin function.
