Example text

Because of other features, it is probably the least used port in normal programming. However, when used as a memory connection, the port has internal pull-up resistors. Port 2 __________________________ Port 2 is another 8-pin I/O connection (pins 21-28). It is less frequently used in normal programming. It is quasi bi-directional, has internal pull-ups, and can sink/source four TTL devices. When 1s are written to the pins, they are pulled high by the internal pull-ups and the pin can be used as an input.

Program and data memory are external chips. The most popular variation has program memory and data memory on board the processor chip. In this family of computers, program memory is separate from data. This is called Harvard architecture and it is the design used by Intel related machines. Mixed memory is Von Neumann’s Princeton architecture. It is the design used by Motorola related machines. Reduced instruction set computers (RISC) have very few instructions but these can access any register in the computer.
