Web2 Answers. The 8085 added two new instruction functions: SIM and RIM. These instructions differ from the 8080 instructions in that each has multiple functions. The SIM instruction sets the interrupt mask and optionally writes one bit of data to the serial interface. The RIM instruction reads one bit from the serial interface (if one is present ... WebEach interrupt type is given a number between 0 to 255 and the address of each interrupt is found by multiplying the type by 4 e.g. for type 11, interrupt address is 11 x 4 = 4410= 0002CH When the 8086 responds to an interrupt, it automatically goes to the specified location in the Interrupt Vector Table in 8086 to get the starting address of interrupt …
