PRODUCTION DATA.
The DAC_FAULT_LSB and DAC_FAULT_MSB registers together make up the DAC_FAULT[13:0] DAC output value. When the diagnostics are enabled, the DAC ouput is driven to the DAC_FAULT[13:0] value in case a power-supply or signal-chain error occurs. The DAC_FAULT[13:0] data is provided in unipolar straight binary format.
The power-supply or signal-chain error indication takes priority over the clamping condition. That means if the DAC output is clamped to either the LOW_CLAMP[13:0] or HIGH_CLAMP[13:0] value and a power-supply or signal-chain error occurs, then the DAC output is driven to the DAC_FAULT[13:0] value.
