18.5 CALIBRATION REGISTERS
BGCALCN: Background Calibration Control
(Address 0x10)
Bit
Bit Symbol
Bit Description
[7:2] Reserved
-
[1:0] BGCALN
Background calibration control – selects scheme for continuous background calibration.
0x0 (default):
BgcalMode0: Background Calibration OFF
0x1:
BgcalMode1: Offset Correction / Gain Estimation
0x2:
BgcalMode2: Offset Correction / Gain Correction
0x3:
BgcalMode3: Offset Estimation / Gain Estimation
SCALCN: System Calibration Control
(Address 0x17)

[1:0] SCALCN
System Calibration Control
When written, set SCALCN to:
0x0 (default):
Normal Mode
0x1:
“System Calibration Offset Coefficient Determination” mode
0x2:
“System Calibration Gain Coefficient Determination” mode
0x3:
Reserved
When read, this bit indicates the system calibration mode is in:
0x0:
Normal Mode
0x1:
"System Calibration Offset Coefficient Determination" mode
0x2:
"System Calibration Gain Coefficient Determination" mode
0x3:
Reserved
Note: when read, this bit will indicate the current System Calibration status. Since this co-
efficient determination mode will only take 1 conversion cycle, reading this register will only
return 0x00, unless this register is read within 1 conversion window.
