Scanning SAR ADC (Scan_ADC)
The Scanning SAR ADC component gives configuration-, schematic-, and firmware-level support for the version of the SAR (‘Successive Approximation Register’) ADC present on some members of the PSoC family. Up to sixteen analog channels (from sources dependent on the specific device) can be automatically scanned, either on demand or continuously, with the results placed in individual result registers. One of the channels may be routed through a 2nd order switched-cap filter. The scan scheduler adjusts internal sampling behavior and clock to accommodate specific settling time and overall scan rate requirements. Averaging can be applied to any channel in a scan.
