R0: Raw ADC value
Register R0 contains the raw value of the analog/digital converter. This is the unchanged analog value prior
to any scaling.
R1: Calibration value - offset
After a calibration, the offset value that was determined is entered in register R1 and used for the correction
calculation.
R2: Calibration value - gain
After a calibration, the gain value that was determined is entered in register R2 and used for the correction
calculation.
R6: Diagnostic register
Status byte SB1 [
}
42] is placed into register R6.
R7: Command register
User code word
For the following commands to be executed, it is first necessary for the user code word, 0x1235, to
be entered into
