Iteration Control Instructions. … WebIf that IR input of the master is unmasked and if that input is a higher priority than any other IR inputs currently being serviced, then the master will send an INT signal to the 8086 INTR input. If the INTR interrupt is enabled, the 8086 will go through its INTR interrupt procedure and sends out two INTA pulses to both the master and the slave. WebApr 8, 2024 · The 8086 has a 4-bit loop counter for multiplication and division. This counter starts at 7 for byte division and 15 for word division, based on the low bit of the opcode. This loop counter allows the microcode to decrement the counter, test for the end, and perform a conditional branch in one micro-operation. cpso james chiang
