c6 input greyed out for 20m2 but 20m2 diagram indicates is available

[peter howarth]

Wanting to program 20m2 device in flowchart, pre selecting ins and outs, but input c6 is greyed out in preselect programming screen,, but datasheet diagram indicates c6 is available as input, is c6 input available as a useable input or not? Regards Peter

Pin C6 is fixed as an input, and it's greyed out because it cannot be reconfigured to an output, so you're fine to use it as an input and no special setup is required.
