4.7.3. Shadow Register Sets

The Number of shadow register sets setting determines whether the Nios® II core implements shadow register sets. The Nios® II core can be configured with up to 63 shadow register sets.

Shadow register sets are available only on the Nios® II/f core.

Note: When the EIC interface and shadow register sets are implemented on the Nios® II core, you must ensure that your software is built with the Nios® II EDS version 9.0 or higher.

For details about shadow register sets, refer to “Registers” in the Programming Model chapter of the Nios® II Processor Reference Handbook.
