Notes:
Regarding input signals
“0” will be captured in the internal register if a “L” level is input to the input pin even once (
➀
of Figure 1-8) during the
data capture interval.
“1” will be captured in the internal register only if a “H” level is maintained (
➁
of Figure 1-8) throughout the data
capture interval.
Therefore, if noise occurs in the input data, implement noise reduction measures with the program and peripheral
devices.
