Detailed Description

Implementation of a interrupt controller for AVR series.

Constructor & Destructor Documentation

◆ ArchAVR_IntCtrl()

ArchAVR_IntCtrl::ArchAVR_IntCtrl ( const ArchAVR_IntCtrlConfig & config )

Member Function Documentation

◆ init()

bool ArchAVR_IntCtrl::init ( Device & device )

overridevirtual

Virtual method called when the device is initialised. This is where the peripheral can allocate its I/O registers, interrupts or connect signals.

Returns: boolean indicates the success of all allocations.

Reimplemented from Peripheral.

◆ ioreg_write_handler()

void ArchAVR_IntCtrl::ioreg_write_handler	(	reg_addr_t	addr,
		const ioreg_write_t &	value
	)

virtual

Virtual method called when the CPU is writing a I/O register allocated by this peripheral. The value has already been written.

Parameters

addr	the register address in I/O space
value	the new register content
