Internal Temperature Value/VDD Value Register LSBs

(Read-Only) [Add. = 03h]

This internal temperature value and VDD value register is an

8-bit read-only register. It stores the 2 LSBs of the 10-bit temp-

erature reading from the internal temperature sensor and also

the 2 LSBs of the 10-bit supply voltage reading.

External Temperature Value and Analog Inputs1 to 4

This is an 8-bit read-only register. Bits D2–D7 store the 2 LSBs

of the analog inputs AIN2–AIN4. Bits D0 and D1 are used to

store the 2 LSBs of either the external temperature value or

AIN1 input value. The type of input for D0 and D1 is selected

by Bits 1:2 of the Control Configuration 1 register.

Analog Inputs 5 to 8 Registers LSBs (Read-Only)

[Add. = 05h]

This is an 8-bit read-only register. Bits D0 to D7 store the 2 LSBs

of the analog inputs AIN5 to AIN8. The MSBs are stored in

Registers 0Ch to 0Fh.

VDD Value Register MSBs (Read-Only) [Address = 06h]

This 8-bit read-only register stores the supply voltage value. The

8 MSBs of the 10-bit value are stored in this register.

Internal Temperature Value Register MSBs (Read-Only)

[Address = 07h]

This 8-bit read-only register stores the internal temperature

value from the internal temperature sensor in twos complement

format. This register stores the 8 MSBs of the 10-bit value.
