Hi,

I would like to confirm about the treatment of unused GPIO.

It is described in AN 80994 as follows.

AN80994

http://www.cypress.com/documentation/application-notes/an80994-design-considerations-electrical-fast...

"Terminate the unused I/O lines to ground or supply through resistors of typical value of 10 k."

We understand that it implements resistors on the unused pins of analog Hi-Z.

Instead of implementing external resistors, Is it effective to pull up/pull donw unused pins in PSoC internal NVL setting?

Regards,

Masashi

"The internal pull up / pull down of PSoC can not obtain the effect of EFT"

The understanding is OK.
