5.4 Register description
The following registers are used for parameterization of the KL3681. They can be read or written via the
register communication [

R0: Raw value A/D­C
Raw value of the A/D converter (X
R
)
R1: Current measuring range / mode
R2: Internal calibration value
R3: Sampling duration

R4: Register page selection register
This register defines which register page is displayed in registers R32 to R63 [ } 35] (default: 0x0000).
The terminal supports two register pages.
• Register page 0 is used to save the configuration data (see from register RP0.R32 [ } 35])
• Register page 1 is used for internal calibration data and manufacturer calibration and must not be
changed by the user!
R6: Diagnostic register
The status byte [ } 28] is mapped to the low­order byte (bit 7 to bit 0) of register R6.
The high­order byte (bit 15 to bit 8) of register R6 is reserved.
