Settings are as follows:
0 PU 1 = Power up complete
1 OR* 1 = Out of range error occurred
2 IS 1 = Invalid scaling detected
3 RTS 1 = Real time sampling BTR timeout
4 CS* 1 = Calibration status

* Channel faults. Channels 1 – 32 (1 to 20hex) loaded in diagnostics data.
If configuration error and 0 in diagnostics data, RTS or autocal values are invalid.
Power up complete
This bit is set when the power up test is complete, no hardware failures were de-
tected, and the module is ready to start processing block transfer write requests and/
