In this application it uses strong internal pullups when emitting 1's.
Port 0 is an 8bit open drain bi-directional I/O port.
written to the them float, and in that state can be used as high impedance inputs.
Port 0 is also the multiplexed low-order address and data bus during accesses to
external program and data memory.
