I/O
Port 0: Port 0 is an 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 must be polarized to VCC or VSS in order to prevent any parasitic
current consumption. Port 0 is also the multiplexed low-order address
and data bus during access to external program and data memory. In this
application, it uses strong internal pull-up when emitting 1s. Port 0 also
inputs the code bytes during EPROM programming. External pull-ups are
required during program verification during which P0 outputs the code
bytes.

I/O
Port 1: Port 1 is an 8-bit bidirectional I/O port with internal pull-ups. Port 1
pins that have 1s written to them are pulled high by the internal pull-ups
and can be used as inputs. As inputs, Port 1 pins that are externally
pulled low will source current because of the internal pull-ups. Port 1 also
receives the low-order address byte during memory programming and
verification.
