Customer question:
"I am having trouble with a line on GPIO Port A. The line is PA1. We are using PA0 and PA1 as inputs. These two ports are also used for a UART. PA0 is the receive and PA1 is the transmit line. The PA0 input works fine configured as an input. PA1 does not. I believe the configuration of the lines is the same for both inputs but PA1 remains high.
Can this line be used as an input? If it can how do I configure it?"
Regards,
Todd Anderson
