Pin
Ping()
The Ping() command verifies if a device is responding at
a particular address. The ADT7488A shows a valid non-zero
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 ADT7488A.

GetIntTemp()
The ADT7488A shows the local temperature of the device
in response to the GetIntTemp() command. The data has a
little endian, 16-bit, twos complement format.
GetExt1Temp()
Prompted   by   the   GetExt1Temp()   command,   the
ADT7488A shows the temperature of Remote Diode 1 in
little endian, 16-bit, twos complement format. The
ADT7488A shows 0x8000 in response to this command if
the external diode is an open or short circuit.
GetExt2Temp()
Prompted by the GetExt2Temp() command, ADT7488A
shows the temperature of Remote Diode 2 in little endian,
16-bit, twos complement format. The ADT7488A shows
0x8000 in response to this command if the external diode is
an open or short circuit.
GetAllTemps()
The ADT7488A shows the local and remote temperatures
in a 6-byte block of data (internal temperature first, followed
by   External 1   temperature,   followed   by   External 2
temperature) in response to a GetAllTemps() command.
SetExtOffset()
This command sets the offset that the ADT7488A 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 ADT7488A 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.
ADT7488A Response to Unsupported Commands
A full list of command codes supported by the
ADT7488A 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 ADT7488A.
The ADT7488A 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 manufacturers use
only, and no data can be written to the device via these
addresses.
Voltage Measurement
The ADT7488A has two external voltage measurement
channels. It can also measure its own supply voltage, V
CC
.
Pins 7 and 8 measure the supplies of the processor core
voltage (V
CCP
), and 2.5 V pins, respectively. The V
CC
supply voltage measurement is carried out through the V
CC
pin (Pin 1). The 2.5 V pin can be used to monitor a chip-set
supply voltage in a computer system.
Analog-to-Digital Converter
All analog inputs are multiplexed into the on-chip,
successive   approximation,   analog-to-digital   converter
(ADC). This has a resolution of 10 bits. The basic input
range is 0 V to 2.25 V, but the inputs have built-in
attenuators to allow measurement of 2.5 V, 3.3 V, 5.0 V,
