Electrical characteristics
All I/Os are CMOS and TTL compliant (no software configuration required), their
characteristics consider the most strict CMOS-technology or TTL parameters:

Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to +/-8 mA, and sink
+20 mA (with a relaxed V
OL
).
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
