SYSOCAL–System Offset Calibration
Description: Initiates a system offset calibration. The input
should be set to 0V, and the ADS1240 and ADS1241 compute
the OCR value that compensates for offset errors. The Offset
Calibration Register (OCR) is updated after this operation. The
user must apply a zero input signal to the appropriate analog
inputs. The OCR register is automatically updated afterwards.

SYSGCAL–System Gain Calibration
Description: Starts the system gain calibration process. For
a system gain calibration, the input should be set to the
reference voltage and the ADS1240 and ADS1241 compute
the FSR value that will compensate for gain errors. The FSR
is updated after this operation. To initiate a system gain
calibration, the user must apply a full-scale input signal to the
appropriate analog inputs. FCR register is updated automati-
cally.

DSYNC–Sync DRDY
Description: Synchronizes the ADS1240 and ADS1241 to an
external event.

SLEEP–Sleep Mode
Description: Puts the ADS1240 and ADS1241 into a low
power sleep mode. To exit sleep mode, issue the WAKEUP
command.
Operands:
None

Data Transfer Sequence:
RESET–Reset to Default Values
Description: Restore the registers to their power-up values.
This command stops the Read Continuous mode.
