I/O
Port 0:
Port 0 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. Port 0 is also the multiplexed low-order address
and data bus during accesses to external program and data memory. In this application it uses
strong internal pull-ups when emitting 1s. Port 0 is also used to input the code byte during
programming and to output the code byte during verification.
