External Temperature Value or Analog Input AIN1
Register MSBs (Read-Only) [Address = 08h]
This 8-bit read-only register stores, if selected, the external
temperature value or the analog input AIN1 value. Selection is
done in Control Configuration 1 register. The external temp-
erature value is stored in twos complement format. The 8 MSBs
of the 10-bit value are stored in this register.

AIN2 Register MSBs (Read) [Address = 09h]
This 8-bit read register contains the 8 MSBs of the AIN2 analog
input voltage word. The value in this register is combined with
Bits D2:3 of the external temperature value and Analog Inputs 1
to 4 register LSBs, Address 04h, to give the full 10-bit conversion
result of the analog value on the AIN2 pin.
