Serial interrupt programming in 8051 plays a significant role since it was used to perform interrupt operation through UART protocol. It plays a significant role in Embedded system Design where the controller has to perform a certain tasks based on the incoming character through the UART. Before go...
Inside the while loop, we have done masking so that the next steps used in the programming can also be utilized. If masking not done the code execution will stop here only. For PORTA ^= 1<<0, here the X-OR operation is used. Its benefit is that it would perform one time high and...
