luna_soc.gateware.core.spiflash.controller module

class luna_soc.gateware.core.spiflash.controller.SPIController(*args, src_loc_at=0, **kwargs)[source]

Bases: Component

Wishbone generic SPI Flash Controller interface.

Provides a generic SPI Controller that can be interfaced using CSRs. Supports multiple access modes with the help of width and mask registers which can be used to configure the PHY into any supported SDR mode (single/dual/quad/octal).

class Cs(*args, src_loc_at=0, **kwargs)[source]

Bases: Register

A CSR register.

Parameters

fieldsdict or list or Field: Collection of register fields. If None (default), a dict is populated from Python variable annotations. fields is used to create a FieldActionMap, FieldActionArray, or FieldAction, depending on its type (dict, list, or Field).

Interface attributes

elementElement: Interface between this register and a CSR bus primitive.

Attributes

fieldFieldActionMap or FieldActionArray or FieldAction: Collection of field instances.
fFieldActionMap or FieldActionArray or FieldAction: Shorthand for Register.field.

Raises

TypeError: If fields is neither None, a dict, a list, or a Field.
ValueError: If fields is not None and at least one variable annotation is a Field.
ValueError: If element.access is not readable and at least one field is readable.
ValueError: If element.access is not writable and at least one field is writable.
