Not a physical register.
VINx Offset Registers (Register 0x10 to Register 0x13)
These read/write 8-bit registers store the offset values for the
relevant input channel.
Temperature Sensor (TSENSEx) Offset Registers
(Register 0x20 to Register 0x22)
These read/write 8-bit registers store the offset values for the
relevant temperature sensor channel.
Current Sensor (ISENSEx) Offset Registers (Register 0x28 to
Register 0x2B)
These read/write 8-bit registers store the offset values for the
relevant current sensor channel.
Unipolar DAC (UNI-VOUTx) Offset Registers (Register 0x30
to Register 0x33)
These read/write registers store the offset values for the
corresponding DAC output. If the copy bit is set to 1, writing to
any of the DAC offset registers sets all the other unipolar DAC
offset registers to the same value.
Bipolar DAC (BI-VOUTx) Offset Registers (Register 0x34 to
Register 0x37)
These read/write registers store the offset values for the
corresponding DAC output. If the copy bit is set to 1, writing to
any of the DAC offset registers sets all the other bipolar DAC
offset registers to the same value. Any write to these registers
affects the DAC range in open-loop mode and the integrator
limit in closed-loop mode.
