Question:
Suppose a PIC is being used with an 8086 MPU. Now, lets say the IR6 interrupt is already in service and not finished yet. Then IR4 interrupt occurs. After the interrupt occurs, we check that the current value of the S5 pin of the 8086, which is currently low. In this case, what will be the value of the In-Service Register (ISR)?
