Command Code Details
ADT7484A/ADT7486A Device Identifier Block
The GetDIB() command retrieves the device identifier
block (DIB), which provides information to identify the
capabilities of the ADP7484A/ADT7486A. The data
returned can be in 8- or 16-byte format. The full 16-bytes of
DIB is detailed in Table 8. 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 8.
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.

Pins
Ping()
The Ping() command verifies if a device is responding at
a particular address. The ADT7484A/ADT7486A show a
valid nonzero FCS in response to the Ping() command when
correctly addressed.

ResetDevice()
This command resets the register map and conversion

the client address of the ADT7484A/ADT7486A.

GetIntTemp()
The ADT7484A/ADT7486A show 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
ADT7484A/ADT7486A show the temperature of the
remote diode in little endian, 16-bit, twos complement
format. The ADT7484A/ADT7486A show 0x8000 in
response to this command if the external diode is an open or
short circuit.
GetAllTemps()
The ADT7484A shows the local and remote temperatures
in a 4-byte block of data (internal temperature first, followed
by External Temperature 1) in response to a GetAllTemps()
command. The ADT7486A shows the local and remote
temperatures in a 6-byte block of data (internal temperature
first, followed by External Temperature 1 and External
Temperature 2) in response to this command.
SetExtOffset()
This command sets the offset that the ADT7484A/
ADT7486A 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 ?28癈 with +0.25癈
resolution.
GetExtOffset()
This command causes the ADT7484A/ADT7486A to
show the offset that they are using to correct errors in the
external diode. The offset value is returned in little endian
format, that is, LSB before MSB.
ADT7484A/ADT7486A Response to Unsupported
Commands
A full list of command codes supported by the
ADT7484A/ADT7486A is given in Table 7. The offset
registers (Command Codes 0xe0 and 0xe1) are the only
registers that the user can write to. The other defined
registers are read only. Writing to Register Addresses 0x03
to 0xdf shows a valid FSC, but no action is taken by the
ADT7484A/ADT7486A. The ADT7484A/ADT7486A
show an invalid FSC if the user attempts to write to the
devices between Command Codes 0xe2 to 0xee and no data
is written to the device. These registers are reserved for the
manufacturers use only, and no data can be written to the
device via these addresses.
