This structure is used to initialize the SAR ADC subsystem.
The SAR ADC subsystem is highly configurable with many options. When calling Cy_SAR_Init, provide a pointer to the structure containing this configuration data. A set of enumerations is provided in this driver to help with configuring this structure.
See the Initialization and Enable section for guidance.
