Pin list
1.
[I/O] column is the direction of a signal.
"I" indicates input, "O" indicates output, and "B" indicates bidirectional.
2.
[Logic] column is the signal logic.
"P" indicates positive logic, "N" indicates negative logic, and "#" indicates that it can be changed by software.
3.
[Unused] column is the connection destination when not in use.
"Open" indicates no connection, "Pull-up" indicates a pull-up connection, and "GN" indicates a direct connection to GND
or a pull-down connection.
Resistance value of 5 to 10 kΩ is recommended.
4.
All signal input pins can input 0 to +5 V level.
5.
All signal output pins can be pulled up to +5 V but cannot be higher than VDD.
Resistance value of 5 kΩ or more is recommended.
No.
