I/O
Port 0: Port 0 is an open-drain, bi-directional 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 Flash 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 bi-directional 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.
