WebThere are three sources of interrupts for 8086: Hardware interrupt- These interrupts occur as signals on the external pins of the microprocessor. 8086 has two pins to accept hardware interrupts, NMI and INTR. Software interrupt- 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 … ctb file not showing up
