AIN6 Register MSBs (Read) [Address = 0Dh]

This 8-bit read register contains the eight MSBs of the AIN6

analog input voltage word. The value in this register is combined

with Bit D2 and Bit D3 of the AIN5 to AIN8 register LSBs,

Address 05h, to give the full 10-bit conversion result of the

analog value on the AIN6 pin.

AIN7 Register MSBs (Read) [Address = 0Eh]

This 8-bit read register contains the eight MSBs of the AIN7

analog input voltage word. The value in this register is combined

with Bit D4 and Bit D5 of the AIN5 to AIN8 register LSBs,

Address 05h, to give the full 10-bit conversion result of the

analog value on the AIN7 pin.

AIN8 Register MSBs (Read) [Address = 0Fh]

This 8-bit read register contains the eight MSBs of the AIN8

analog input voltage word. The value in this register is

combined with Bit D6 and Bit D7 of the AIN5 to AIN8 register

LSBs, Address 05h, to give the full 10-bit conversion result of

the analog value on the AIN8 pin.

Control Configuration 1 Register (Read/Write)

[Address = 18h]

This configuration register is an 8-bit read/write register that is

used to set up some of the operating modes of the ADT7411.

Table 29.

Bit Function

C0 This bit enables/disables conversions in round robin

and single-channel mode. ADT7411 powers up in round

robin mode, but monitoring is not initiated until this bit

is set. Default = 0.

0 = Stop monitoring.

1 = Start monitoring.

C2:C1 Selects between the two different analog inputs on

Pin 7 and Pin 8. The ADT7411 powers up with AIN1 and

AIN2 selected.

00: AIN1 and AIN2 selected.

01: Undefined.

10: External TDM selected.

11: Undefined.

C3 Reserved. Write 1 only to this bit.

C4 Reserved. Write 0 only.

C5 0: Enable INT/INT output.

1: Disable INT/INT output.

C6 Configures INT/INT output polarity.

0: Active low.

1: Active high.

PD Power-Down Bit. Setting this bit to 1 puts the ADT7411

into standby mode. In this mode, the analog circuitry

is fully powered down, but the serial interface is still

operational. To power up the part again, write 0 to this bit.

Control Configuration 2 Register (Read/Write)

[Address = 19h]

This configuration register is an 8-bit read/write register that is

used to set up some of the operating modes of the ADT7411.
