Command Code Details
ADT7485A Device Identifier Block
The GetDIB() command retrieves the device identifier block
(DIB), which provides information to identify the capabilities of
the ADT7485A. 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 ADT7485A shows a valid nonzero FCS
in response to the Ping() command when correctly addressed.

GetIntTemp()
The ADT7485A shows the local temperature of the device in
response to the GetIntTemp() command. The data has a little
endian, 16-bit, twos complement format.
GetExtTemp()
Prompted by the GetExtTemp() command, the ADT7485A shows
the temperature of the remote diode in little endian, 16-bit, twos
complement format. The ADT7485A shows 0x8000 in response
to this command if the external diode is an open or short circuit.
GetAllTemps()
The ADT7485A 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 ADT7485A will use to
correct errors in the external diode. The offset is set in little
endian, 16-bit, twos complement format. The maximum offset
is ±128°C with +0.25°C resolution.
GetExtOffset()
This command causes the ADT7485A 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.
ADT7485A Response to Unsupported Commands
A full list of command codes supported by the ADT7485A 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 ADT7485A. The ADT7485A 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.
