VCC Supply voltage Port 1 receives the low-order address bytes during EPROM programming and verifying Port 2 Port 2 is an 8-bit bidirectional I O port with internal pullups The Port 2 output buffers can drive LS TTL inputs Port 2 pins that have 1’s written to them are pulled high by the internal pullups and in that state can be used as inputs As inputs Port 2 pins that are externally pulled low will source current (IIL on the data sheet) because of the internal pullups Port 2 emits the high-or
