Hi, I am developing a data transmission circuit using the Cypress EZ-USB development kit. I have a question about setting register. When I unenable a certain pin, for example, CLKOUT pin, it have to be 0 Voltage, I think. But although the CLKOUT pin become to be float, it still outputs 2.5 Volt. Is it correct? Or, because of wrong firmware I made, it become to
2.5 Volt, not to 0 Volt? I am a beginner, so I have to study hard about USB. But if you help me, it is very helpful for me. Please teach me. Thank you for any help. Bye!!- posted
