Which of the following statements is false?
| For an 8259A controller the WR' pin is used by 8259A to write into the 8086
]After the first acknowledgement pulse, the type number of the interrupt will be uploaded on the data bus
For an 8259A controller the RD' pin is used by 8086 to read from the 8259A
| If value of IMR is 11111111, then all the interrupts are unmasked
| The main idea behind using a pic is to increase to number of interrupts
If value of IMR is 00000011, ISR is 00000100 and then you check the value of IRR is 11111110, in this
case the 8086 would be busy with which interrupt?
IRR2
IRR7
IRR6
IRR1
