Must be logic 0 for these commands.
See table below.
CS2-CS0 provide the address of one of the eight physical
channels. These bits are used to access the calibration regis-
ters associated with respective channels.
Note: These bits are ignored when reading the data register.

See table above.
Must be logic 1 for these commands.
These bits are used as pointers to the Setups.
Note: The MC bit, must be logic 0 for these bits to take effect.
When MC = 1, these bits are ignored. The LP, MC, and RC
bits in the configuration register are ignored during calibra-
tion.
