SYSOCAL
System Offset Calibration
Description:
Starts the system offset calibration process. For
a system offset calibration the input should be set to 0V
differential, and the ADS1217 computes the OCR register
value that will compensate for offset errors. The Offset Control
Register (OCR) is updated after this operation.

SYSGCAL
System Gain Calibration
Description:
Starts the system gain calibration process. For
a system gain calibration, the differential input should be set to
the reference voltage and the ADS1217 computes the FSR
register value that will compensate for gain errors. The FSR is
updated after this operation.

Calculate Checksum
for all RAM Banks
CSARAM
Description:
Calculate the checksum of all RAM Banks. The
checksum is calculated as a sum of all the bytes with the carry
ignored. All bits are included in the checksum calculation, there
is no masking of bits.
