Tool/software:
Hi,
When using the whole circuit in a bidirectional manner, could you please tell me the recommended method for handling unused pins when some PINs are not used?
Normally, unused inputs would be VCC or GND, but DIR may change to HI/Low from time to time.
In such a case, would a pull-up or pull-down resistor of around 10k~47kΩ be used?
Best regards,
Hiroshi
