bool Pit::irq ( irq_id_t  number, InterruptState &  state  )

privatevirtual

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

Note

If this function returns false you have to call IrqManager::acknowledgeIrq() when you removed the interrupt reason.

Parameters

[in]

number

the irq number

Returns

should return true, if the interrupt reason was removed, or false otherwise

Implements IrqHandler.
