VCC Supply voltage during normal Idle and Power Down operations VSS Circuit ground Port 0 Port 0 is an 8-bit open drain bidirectional I O port As an output port each pin can sink several LS TTL inputs Port 0 pins that have 1’s written to 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 memory In this application it uses strong internal pullups when emitting 1’s Port 0 also receives the code
