class ArchAVR_ExtInt : public Peripheral, public InterruptHandler, public SignalHook

Implementation of a model for a External Interrupts peripheral for AVR series.

Public Types

enum SignalId

Values:

enumerator Signal_ExtInt
enumerator Signal_PinChange

Public Functions

explicit ArchAVR_ExtInt(const ArchAVR_ExtIntConfig &config)
virtual bool init(Device &device) override

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.

virtual void reset() override

Virtual method called when the device is reset. Note that resetting I/O registers is only necessary here if their reset value is not zero.

virtual bool ctlreq(ctlreq_id_t req, ctlreq_data_t *data) override

Virtual method called for a CTL request. The method must return true if the request has been processed.

virtual void ioreg_write_handler(reg_addr_t addr, const ioreg_write_t &data) override

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

virtual void interrupt_ack_handler(int_vect_t vector) override

Callback method called when a vector has been ACK’ed by the CPU. (i.e. the CPU is about to jump to the corresponding vector table entry)

The default implementation does nothing.

virtual void raised(const signal_data_t &sigdata, int hooktag) override

Pure virtual callback called during signal raises.

Parameters:

  • sigdata – Data structure passed on when raising a signal

  • hooktag – integer passed on when connecting a hook to a signal. For hooks connected to several signals, it provides a mean to identify the caller.
