Method Detail

requestIRQNumber

public abstract int requestIRQNumber(AbstractModule module)

Returns an IRQ number.

Parameters:

module - that would like to have an IRQ number

Returns:

int IRQ number between 1 to 16, or -1 if not allowed/possible

---

clearIRQ

public abstract void clearIRQ(int irqNumber)

Lowers an interrupt request (IRQ) of given IRQ number

Parameters:

irqNumber -

---

setIRQ

public abstract void setIRQ(int irqNumber)

Raises an interrupt request (IRQ) of given IRQ number

Parameters:

irqNumber -

---

interruptAcknowledge

public abstract int interruptAcknowledge()

Acknowledges an interrupt request from PIC by CPU Note: only the CPU can acknowledge an interrupt

Returns:

int address defining the jump address for handling the IRQ by the CPU
