Serial interrupt programming in 8051 plays a significant role since it was used to perform interrupt operation through UART protocol. The "standard C library" should always come with whatever compiler you use -otherwise it's not really a C compiler. Basically 8051 controller is Mask programmable means it will programmed at the time of manufacturing and will not programmed again, there is a derivative of 8051 microcontroller, 89c51 micro controller which is re-programmable. serial. It will be much easier for a C programmer to switch to 8051 C because he/she only needs to learn the extensions to the language and to deal with missing parts of the standard library. TB8 9th data bit that will be transmitted in Mode 2 and 3. You will find that your project development time using C is lower and that your maintenance time using C is also lower. according to me C Language is more difficulty and Lengthy to Keil was founded in 1982 by Günter and Reinhard Keil for the development tools, designed specifically for the 8051 microcontroller.
