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.
Port 2
P2 is an 8-bit bidirectional I/O port with internal pull-ups.
