You must first of all glance over the project here. Each consists of a latch Special Function Registers P0 through P3an output driver, and an input buffer. Filed under DescriptionHow Stuff Works? Telecommunication and Electronics Projects. Views Read Edit View history. You can help Wikipedia by expanding it.
Otherwise the port pin is stuck at 0. This allows a great amount of legacy code to be reused without modification in new applications.
Convert to Blogger by SimplexDesign. Based on the Intel core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, their low unit cost, and the availability of these chips in DIL DIP packages.
Blog Archive The alternate functions can only be activated if the corresponding bit latch in the port SFR contains a 1. The output drivers of Ports 0 and 2, and the input buffers of Port 0, are used in accesses to external memory.
Those ports can be used to output DATA and orders do other devices, or to read the state of a sensor, or a switch.
It is the CPU that will Read the program from the FLASH memory and Execute it by interacting with the different peripherals Diagram below shows the pin configuration of the 89S52, where the function of each pin is written next to it, and, if it exists, the dual function is written between brackets.
Port 2 outputs the high byte of the external memory address when the address is 16 bits wide. Posted by Muhammad Ahmed on Shortly, RAM is used to store variable during program execution, while the EEPROM memory is used to store the program itself, that’s why it is often referred to as the ‘program memory’.
From Wikipedia, the free encyclopedia. Diagram below shows the pin configuration of the 89S52, where the function microconrtoller each pin is written next to it, and, if it exists, the dual function is written between brackets.
Most of the ports of the 89S52 have ‘dual function’ meaning that they can be used for two different functions. Retrieved from ” https: Newer Post Older Post Home. Designed by Gabfire Themes.

There are two different memory types: Feel free to leave a response. In this application, Port 0 outputs the low byte of the external memory address, time-multiplexed with the byte being written or read. Hello, this very post is related to the RPM meter project.
