Command Code Details
ADT7485 Device Identifier Block
The GetDIB() command retrieves the device identifier block
(DIB), which provides information to identify the capabilities of
the ADT7485. The data returned can be in 8- or 16-byte format.
The full 16 bytes of DIB is detailed in Table 7. The 8-byte format
involves the first eight bytes described in this table. Byte-sized
data is returned in the respective fields as it appears in Table 7.
Word-sized data, including vendor ID, device ID, and data
values use little endian format, that is, the LSB is returned first,
followed by the MSB.

Ping()
The Ping() command verifies if a device is responding at a
particular address. The ADT7485 shows a valid nonzero FCS in
response to the Ping() command when correctly addressed.

ResetDevice()
This command resets the register map and conversion
controller. The reset command can be global or directed at the
client address of the ADT7485.

GetIntTemp()
The ADT7485 shows the local temperature of the device in
response to the GetIntTemp() command. The data has a little
endian, 16-bit, twos compliment format.
GetExtTemp()
Prompted by the GetExtTemp() command, the ADT7485 shows
the temperature of the remote diode in little endian, 16-bit,
twos compliment format. The ADT7485 shows 0x8000 in
response to this command if the external diode is an open or
short circuit.
GetAllTemps()
The ADT7485 shows the local and remote temperatures in a
4-byte block of data (internal temperature first, followed by
external temperature) in response to a GetAllTemps()
command.
SetExtOffset()
This command sets the offset that the ADT7485 will use to
correct errors in the external diode. The offset is set in little
endian, 16-bit, twos compliment format. The maximum offset is
±128°C with +0.25°C resolution.
GetExtOffset()
This command causes the ADT7485 to show the offset that it is
using to correct errors in the external diode. The offset value is
returned in little endian format, that is, LSB before MSB.
ADT7485 Response to Unsupported Commands
A full list of command codes supported by the ADT7485 is
given in Table 6. The offset registers (Command Code 0xe0) are
the only registers that the user can write to. The other defined
registers are read only. Writing to Register Addresses 0x02,
0x09, and 0x15 to 0xdf shows a valid FSC, but no action is taken
by the ADT7485. The ADT7485 shows an invalid FSC if the
user attempts to write to the device between Command Codes
0xe2 to 0xee. These registers are reserved for the manufacturer’s
use only, and no data can be written to the device via these
addresses.
