The document discusses the architecture of microcontrollers. It describes the hardware components of the PIC16F877A microcontroller, including its I/O ports, power supply connections, and reset button. It also outlines the main connections, software requirements including Proteus, Micro C Pro and a burner program, and hardware requirements such as a PC, programmer, and other electronic components needed to interface with the microcontroller.

- 9. IO ports of MCUs are 8 bit data registers that connect MCUs to outside world. IO ports in PIC16F877A are 5 ports named " PORT A,PORTB PORT C,PORT D,PORT E. IO ports of MCUs are "Bidirectional" that the single port can be used either input or output. The register for each port is used to control port data direction flow called TRISx ,any pin could be an input pin if its equivalent TRISx bit is 1 and output if 0.
