Function
P0.7:0
P1.7:0
Port 0
P0 is an 8-bit open-drain bidirectional I/O port. Port 0 pins that have 1s
I/O 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 VDD or VSS.
I/O
Port 1
P1 is an 8-bit bidirectional I/O port with internal pull-ups.
