Member Function Documentation

void OpenPic::acknowledgeIrq ( irq_id_t  Id )

virtual

Acknoledge the IRQ reception, in case you returned false in the IrqHandler::irq() function. If this is not called there won't be any following irqs.

Parameters

[in]

Id

the irq's identifier

Implements IrqManager.

Here is the caller graph for this function:

bool OpenPic::initialise

(

)

Initialises the PIC hardware and registers the interrupts with the InterruptManager.

Returns

true, if successfull, false otherwise

Todo:

Set up timers.

Called when the handler is registered with the interrupt manager and the interrupt occurred

Parameters

[in]	nInterruptNumber	the interrupt number
[in]	state	reference to the state before the interrupt

Implements InterruptHandler.
