ADT7316/ADT7317/ADT7318
External T
This limit register is an 8-bit, read/write register that stores the
twos complement of the external temperature lower limit that
causes an interrupt and activates the INT/ INT output (if enabled).
For this to happen, the measured external temperature value
has to be more negative than or equal to the value in this regis-
ter. As it is an 8-bit register, the temperature resolution is 1°C.
The default value is 0°C.

Device ID Register (Read-Only) [Address 0x4D]
This 8-bit, read-only register indicates which part the device is
in the model range. ADT7316 = 0x01, ADT7317 = 0x09, and
ADT7318 = 0x05.
Default settings at power-up.

Manufacturer’s ID Register (Read-Only) [Address 0x4E]
This register contains the manufacturers identification number.
Analog Devices, Inc. ’ s ID is 0x41.
Silicon Revision Register (Read-Only) [Address 0x4F]
This register is divided into the 4 LSBs representing the stepping
and the 4 MSBs representing the version. The stepping contains
the manufacturer’s code for minor revisions or steppings to the
silicon. The version is the ADT7316/ADT7317/ ADT7318
version number.
SPI Lock Status Register (Read-Only) [Address 0x7F]
Bit D0 (LSB) of this read-only register indicates whether the SPI
interface is locked. Writing to this register causes the device to
malfunction. The default value is 0x00.
0 = I
1 = SPI interface selected and locked.
