IRQ 0 - System timer. IRQ 1 - Keyboard. IRQ 2 - Cascaded signals from IRQs 8-15. IRQ 3 - COM2 (Default) and COM4 (User) serial ports
IRQ 4 - COM1 (Default) and COM3 (User) serial ports
IRQ 5 - LPT2 Parallel Port 2 or sound card
IRQ 6 - Floppy disk controller
IRQ 7 - LPT1 Parallel Port 1 or sound card (8-bit Sound Blaster and compatibles) IRQ 8 - Real time clock
IRQ 9 - Free / Open interrupt / Available / SCSI. Any devices configured to use IRQ 2 will actually be using IRQ 9.
IRQ 10 - Free
IRQ 11 - Free IRQ 12 - PS/2 connector Mouse. IRQ 13 - ISA / Math Co-Processor
IRQ 14 - Primary IDE. If no Primary IDE this can be changed
IRQ 15 - Secondary IDE These are just a set of standard IRQs. For much more detail check our Ralf Brown's list located at http://www.cs.cmu.edu/~ralf/files.html
What else can I help you with?
What are the pins used to control interrupts?
The pins used to control interrupts in the 8085 are INTR/INTA, RST5.5, RST6.5, RST7.5, and TRAP.
What punctuation is used to set off material that interrupts?
Parentheses or dashes are typically used to set off material that interrupts the flow of a sentence.
What are the names of the trench support sytems used in construction?
trench boxes
Type of indent in a reference list?
A hanging indent is used in a refrence list.
What punctuation is used with an idea that interrupts a sentence and is very noticeable?

Which interrupts are usually used for the hard disk controller?
IRQ 14
What are the instructions used to control the interrupts?
DI, EI, RIM, and SIM.
Type of indent used in a referance list?
A hanging indent is used in a reference list.
What type of indent is used in a reference list for APA papers?
A hanging indent is used in a reference list for APA papers.
Which register is used to set priority for interrupts?
The 8085 does not have an adjustable priority interrupt schema. You can only turn interrupts off, and mask certain interrupts, such as RST5.5, RST6.5, and RST7.5. However, that said, you can implement a priority schema, of sorts, within these interrupts, including INTR, by using the SIM instruction. You can't change the basic priority but you can disable certain interrupts while others are being serviced, if you so choose.
What is the purpose of RST instruction in microprocessor?
Special restart instruction used with interrupts
Type of intent used in a ref list?
Hanging indent.
