<p><b>Cluster</b> adds a new and optional sub-level to the CMSIS SVD <em>registers</em> level. A cluster describes a sequence of registers within a peripheral. A cluster has an base offset relative to the base address of the peripheral. All registers within a cluster specify their address offset relative to the cluster base address. <em>Register</em> and <em>cluster</em> sections can occur in an arbitrary order. This feature, targeted at the generation of device header files, is useful to create a C data structure within the peripheral structure type, rather than describing all registers of a peripheral in a flat structure.</p>
