WebThe 8051 microcontroller can recognize five different events that cause the main program to interrupt from the normal execution. These five sources of interrupts in 8051are: Timer 0 overflow interrupt- TF0. Timer 1 overflow interrupt- TF1. External hardware interrupt- INT0. External hardware interrupt- INT1. Serial communication interrupt- RI/TI. WebJun 27, 2024 · Arithmetic group in 8051 Microprocessor 8085 In 8051 Microcontroller there are 24 different instructions under the Arithmetic Group. In total there are 64 opcodes. The Carry Flag (CY), Auxiliary Carry (AC)and Overflow flag (OV) are affected based on the result of ADD, ADDC, SUBB etc. instructions.
WebThe 8051 provides powerful addressing of its internal memory space. Any location can be incremented or decremented using direct addressing without going through the accumulator. For example, if internal RAM location 7FH contains 40H, then the instruction. INC 7FH. Increments this value, leaving 41H in location 7FH.
