4. Low/High Point Calibration DO
Low/High Point Calibration status register explains if calibration process is executed successfully.
If any error regarding the low/high point was present this is identified by bit content change (0 to
1) in specific Hold Registers (low point: HR5157 and high point: HR5189). The definition of each
bit is explained in table 4.1.
