unor4: fix NUM_DIGITAL_PINS macro

facchinm · facchinm · commit 80a8317a1605 · 2023-08-25T09:45:20.000+02:00
The macro represents the number of pins that can be actively used "directly". Since A4/A5 are shared with SDA/SCL, the total number of unique gpios on UNO R4 headers is indeed 14+6 NUM_DIGITAL_PINS is currently unused in the core (better to use PINCOUNT #107 for any safety check)
