Part Number: TCA6408A-Q1
Hi Team,
I am using TCA6408A-Q1 part only for HIGH and LOW detection by using a ON-OFF Switch at P0 and P1 Pin. I have pulled it up with 3.3V and added on-off switch with it for sensing High and Low (for more clarification i have attached my designed circuit). I have some doubt can i use only 2 GPIOs (P0 and P1) pin for sensing HIGH and LOW ? If yes then fine. if Not, then Which 2 GPIOs pin can be used for sensing HIGH and LOW logic from Switches. As i do not want to use rest of all 6 GPIO pins (P2,P3,P4,P5,P6 and P7) so i have also pulled it up.
Can you please help me for same issue.
Thanks
