Tool/software:

Dear Specialists,

My customer would like to know the I/O_3 pin configuration when not used.

The customer is used for SPI communication.

Can the I/O_3 pin be left open.

I appreciate your great help in advance.

Best regards,

Shinichi

Hi Shinichi-san,

If you are in serial SPI mode then I/O_3 is unused. You may leave it open.
