WREG: Write to Register
Description: These two opcode bytes write register data. The Register Write command is a two-byte opcode
followed by the register data. The first byte contains the command opcode and the register address. The second
byte of the opcode specifies the number of registers to write
– 1.
First opcode byte: 0100 rrrr, where rrrr is the starting register address.
Second opcode byte: 0000 nnnn, where nnnn is the number of registers to write
After the opcode bytes, the register data follows (in MSB-first format).
(1) CS may be tied low.
Figure 63. WREG Command Example: Write Two Registers Starting from 00h (CONFIG0)
(OPCODE 1 = 0100 0000, OPCODE 2 = 0000 0001)
OFSCAL: Offset Calibration
Description: This command performs an offset calibration. Apply a zero signal and allow the input to stabilize
before sending the command; see the Calibration section for more details.
GANCAL: Gain Calibration
Description: This command performs a gain calibration. Apply a full-scale signal and allow the input to stabilize
before sending the command; see the Calibration section for more details.
