dimElementGroup
Element Groups

The SVD specification supports the array-of-registers concept. The single register description gets duplicated automatically into an array. The size of the array is specified by the <dim> element. The register names can be composed by the register name and an index-specific substring defined in <dimIndex>. The <dimIncrement> specifies the address offset between two registers. The elements below can be used to generate an array of registers.

Element Name | Description | Type | Occurrence
--- | --- | --- | ---
dim | The value defines the number of elements in an array of registers. | scaledNonNegativeInteger | 1..1
dimIncrement | If dim is specified, this element becomes mandatory. The element specifies the address increment in between two neighboring registers of the register array in the address map. | scaledNonNegativeInteger | 1..1
dimIndex | Specifies the substrings that replaces the %s placeholder within the register name. By default, the index is a decimal value starting with 0 for the first register. | dimIndexType | 0..1

# Examples:

...
<register>
<dim>6</dim>
<dimIncrement>4</dimIncrement>
<dimIndex>A,B,C,D,E,Z</dimIndex>
<name>GPIO_%s_CTRL</name>
...
</register>

The code above generates: => GPIO_A_CTRL, GPIO_B_CTRL, GPIO_C_CTRL, GPIO_D_CTRL, GPIO_E_CTRL, GPIO_Z_CTRL

...
<register>
<dim>4</dim>
<dimIncrement>4</dimIncrement>
<dimIndex>3-6</dimIndex>
<name>IRQ%s</name>
...
</register>

The example above generates: => IRQ3, IRQ4, IRQ5, IRQ6
