Public Member Functions
satcat5::cfg::IoStatus	read (unsigned regaddr, u32 &val) override
	Basic single-register read operation.

satcat5::cfg::IoStatus	write (unsigned regaddr, u32 wrval) override
	Basic single-register write operation.

void	irq_poll ()
	Make the "irq_poll" method accessible.

void	add_device (unsigned devaddr, satcat5::cfg::ConfigBus &cfg)
	Register a handler for a specific device address.

satcat5::cfg::ConfigBus &	get_device (unsigned devaddr)
	Access the designated device handler, by device-address.

virtual satcat5::cfg::IoStatus	read_array (unsigned regaddr, unsigned count, u32 *result)
	Bulk-read with auto-increment (regaddr, regaddr+1, ...) Bulk read/write operations are more efficient when controlling ConfigBus peripherals over a network interface.

virtual satcat5::cfg::IoStatus	read_repeat (unsigned regaddr, unsigned count, u32 *result)
	Bulk-read the same register N times.

virtual satcat5::cfg::IoStatus	write_array (unsigned regaddr, unsigned count, const u32 *data)
	Bulk-write with auto-increment (regaddr, regaddr+1, ...)

virtual satcat5::cfg::IoStatus	write_repeat (unsigned regaddr, unsigned count, const u32 *data)
	Bulk-write the same register N times.

unsigned	get_regaddr (unsigned dev, unsigned reg) const
	Convert device + register to combined address.

void	register_irq (satcat5::cfg::Interrupt *obj)
	Add an interrupt handler. More...

void	unregister_irq (satcat5::cfg::Interrupt *obj)
	Remove an interrupt handler.

unsigned	count_irq () const
	Count attached interrupt handlers.

satcat5::cfg::Register	get_register (unsigned dev, unsigned reg=0)
	Create register-map object for the given device address. More...

Member Function Documentation

◆ get_register()

Register ConfigBus::get_register	(	unsigned	dev,
		unsigned	reg = `0`
	)

inherited

Create register-map object for the given device address.

(Or for a specific register, if the register address is specified.)

Definition at line 101 of file cfgbus_core.cc.

◆ register_irq()

void ConfigBus::register_irq ( satcat5::cfg::Interrupt * obj )

inherited

Add an interrupt handler.

Each ConfigBus interface has a single interrupt signal, which is the logical OR of interrupts from all attached peripherals. When any peripheral raises its interrupt signal, call irq_poll().
