Hi,
I would like to confirm about the treatment of unused GPIO.
It is described in AN 80994 as follows.
AN80994
"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.
