XPS Delta-Sigma Digital to Analog Converter (DAC) (v1.01a)
a design that utilizes only the resources required by the system and runs at the best possible
performance. Table 2 lists the features that are parameterizable in the XPS Delta-Sigma DAC core.

1. No default value will be specified to insure that the actual value is set, i.e. if the value is not set, a compiler error will
be generated.
2. For example, C_BASEADDR = 0xE0000000, C_HIGHADDR = 0xE00001FF
3. Address range specified by C_BASEADDR and C_HIGHADDR must be at least 0X200 and must be a power of 2.
4. With C_FULL_RANGE set to 0, the DAC output will be (2ⁿ - 1)/2ⁿ. Where n is the number of DAC bits,
C_NUM_DAC_BITS.
