External Temperature Value and Analog Input 1 to
Analog Input 4 Register LSBs (Read-Only) [Address = 0x04]
This is an 8-bit, read-only register. Bits[D2:D7] store the two
LSBs of the analog inputs AIN2 to AIN4. Bits[D0:D1] store the
two LSBs of either the external temperature value or AIN1 input
value. The type of input for D0 and D1 is selected by Bits[C1:C2]
of the Control Configuration Register 1.

AIN2 Register MSBs (Read) [Address = 0x09]
This 8-bit read register contains the eight MSBs of the AIN2
analog input voltage word. The value in this register is combined
with Bits[D2:D3] of the external temperature value and Analog
Input 1 to Analog Input 4 register LSBs, Address 0x04, to give the
