gateware manual: wrong data format reported for channel status registers
The gateware manual states that the data format for channel status registers is 2's complement.
This is a (semi) false statement, the actual data format depends on the configuration of the ADC; it can be either "offset binary", or 2's complement.
By default, after power-up, the ADC is configured for "offset binary". On the other hand, our driver will always reconfigure it for 2's complement if/when loaded.
The gateware manual should be updated to better describe this, to avoid confusing users of the gateware who are not using our driver and expect to see 2's complement values, but get the default offset binary instead.
