Span Cal
Register
A 16-Bit value whose bit position when
set indicates the channel to be calibrated
for span. For example: to calibrate span
of channel 0, write 0001H to this register.
To calibrate span of channel 5, write
0020H to this register.
IMPORTANT:
You must FIRST write
5E2AH into the Calibration Access
Register (Register 40021) before
attempting calibration.

Zero Cal
Register
A 16-Bit value whose bit position when
set indicates the channel to be calibrated
for zero. For example: to calibrate zero
of channel 0, write 0001H to this register.
To calibrate zero of channel 5, write
0020H to this register.
IMPORTANT:
You must FIRST write
5E2AH into the Calibration Access
Register (Register 40021) before
attempting calibration.
