Description
These pins are part of Port 0, which is an 8-bit open-d
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.
