#156785 - High Impedence GPIO |
Hi All,
I am using a usb chip having 8051 core(CY7C68013). How to configure the Ports as high impedance output? More clearly.. if we initialize control registers as OEx=0x00, it ll work as input. if we initialize control registers as OEx=0xFF, it ll work as output. But for high impedance state cypress is saying that-"By configuring port pin as output and disabling the output, it is possible to keep pin in high impedance". Here problem is how to disable the out put? Thanks in advance rishi |
