Description
Port 0
P0 is an 8-bit open-drain bidirectional I/O port. Port 0 pins that have 1s written
to them float and can be used as high impedance inputs. To avoid any parasitic
current consumption, floating P0 inputs must be polarized to V
Port 1
P1 is an 8-bit bidirectional I/O port with internal pull-ups.
