[minoru_nishimura]

Hello,

I have a question about CS1 on Port A.
When I set the serial flash port B selection to 0, are the following settings correct?

1 – Enable CS1 on Port A
0 – Disable CS1 on Port B

Regards,

Nomu

Hi Igor

I have an additional question,
Will Serial flash A2 stop working with the following settings?

0 – Port B is not used.

0 – Disable CS1 on Port A

0 – Disable CS1 on Port B

Hi Nomu

with "Disable CS1 on Port A" setting only CS0 port A will continue to work.

Hi Igor

I have an additional question,
Is CS0 port A the same as QSPIn_A_SS0_B?
