Quadruple processing
The timer up-counts all rising and falling edges to the TA4
the relationship that the TA4
input signal is “H” level.
The timer down-counts all rising and falling edges to the TA4
has the relationship that the TA4
pin’s input signal is “H” level. (Refer to Figure 5.4.8.)
Table 5.4.3 lists the input signals to the TA4
selected.
