P0.0 to P0.7
I/O
Port 0: Port 0 is an 8-bit open drain bidirectional I/O port.
Port 0 pins that have ‘1’s written to them oat, and in this
state can be used as high-impedance inputs. Port 0 is also
the multiplexed low-order address and data bus during
accesses to external code and data memory. In this
application, it uses strong internal pull-ups when
transitioning to ‘1’s. Port 0 also receives the code bytes
during the external host mode programming, and outputs
the code bytes during the external host mode verication.
External pull-ups are required during program verication
or as a general purpose I/O port.

P1.0 to P1.7
I/O with
internal
pull-up
Port 1: Port 1 is an 8-bit bidirectional I/O port with internal
pull-ups. The Port 1 pins are pulled high by the internal
pull-ups when ‘1’s are written to them and can be used as
inputs in this state. As inputs, Port 1 pins that are
externally pulled LOW will source current (IIL) because of
the internal pull-ups. P1.5, P1.6, P1.7 have high current
drive of 16 mA. Port 1 also receives the low-order address
bytes during the external host mode programming and
verication.
