EP9302 ADC
From embeddedTS Manuals
The Cirrus EP9302 features a 5 channel, 12-bit Analog to Digital Converter with an analog multiplexor, with an input range of 0 to 3.3 V. On the TS-7200, only the top and bottom channels (ADC0 and ADC4) are brought out on the DIO1 Header. We have an example of using the EP9302 ADC here.
