I2C Slave pin assigment
I have CY8CKIT-003. I2C Slave Spec says, there is any pin available for this function.
I'm trying with pins P4-SDA and P4[6} _SCL pins (according to example project).
Psoc Creator however doesn't allow such assignment saying:
"Error: apr.M0010: IO "SCL_S(0)" cannot be placed into "P4" because the pin does not support the features required by the IO. (App=cydsfit)"
As far as I figured out only hardware dedicated pins work (P12-0 and P12-1)
And it's regardles of configuration (UDB nor Fixed FUnction)
Does anyone know why?
Template projects reccomends open drain low (can I use resitive pullup?)
