Electrical characteristics
Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to ±8 mA, and sink or
source up to ±20 mA with the non-standard V
In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in
