Description
These pins are part of Port 0, which is an 8-bit open-drain bidirectional I/O port.
Port 0 pins that have 1s written to them float, and, in that state, can be used as
high impedance inputs. An external pull-up resistor is required on P0 outputs to
force a valid logic high level externally. Port 0 is also the multiplexed low-order
address and data bus during accesses to external data memory. In this
application, Port 0 uses strong internal pull-ups when emitting 1s.
