Extracted text: B. Choose the correct answer: 1) If we have one master interrupt controller connected with 2 slave interrupt controllers, then the maximum number of devices (interrupt requests) that can be connected is: 22 24 26 16 64 2) If two salves are connected to a master 8259 PIC at IR3 and IR4 then the ICW3 of the master should be 03H зон OCH сон None of these 3) in 8259, if automatic end of interrupt with rotating priority is required then the AEOI should be set to 0 in ICW4 True False
