PRODUCTION DATA.
There are two functional modes in the PGA302: A Running mode of operation where the digital processing logic is enabled and the Reset mode where the digital processing logic is in reset.
In the Running mode, the I2C and OWI digital interfaces are not allowed to access the PGA302 device memory space. The only communication with the device can be established by accessing the COMBUF communication buffer registers.
The Reset mode is generally used for PGA302 device configuration. In this mode, the I2C or OWI interfaces are allowed to read and write to the device memory. In this mode, the digital processing logic is in reset which means that no device internal signal processing is performed therefore no output data is being generated from the device itself.
