    USBIO pins - CAN bus?

      We routed a board using the USBIO pins for the CAN RX and TX lines not realizing that those pins can only be set as Strong Drive or Open Drain, Drives Low. It looks like the RX pin for CAN has to be high impedance digital. 


      Is there any work around to this? I don't think there is but I figured if anyone knew it would be the users here. I tried running it out and back in through 2 extra pins we ran out but that didn't work. 


      We will have to remake the boards anyways but it would be nice if it could get working without a wire soldered on to test the rest of the functionality.


      Thanks for any insight! The device is a PSoC 5LP CY8C5888LTI-LP097
