I am A student and I need to design A 8051 program that uses the serial interrupt by using uart it is only a simulation , according to my book it is interrupt 4 but when I send something to trigger the RI flag my program does not jump to the interrupt and it is in a while(1) loop in my main function. Any advice or help?
do you have 2 bits
I am not sure what you mean with 2 bits I made the EA 1 ? But I can IE a value of 0x08 to activate the serial interrupt?
both what you say is ONE bit
