PRELIMINARY TECHNICAL DATA
interface is designed to allow the part to be interfaced to
systems that provide a serial clock that is synchronized to
the serial data.
There are two types of serial operations, a read and a
write. Command words are used to distinguish between a
read and a write operation. These command words are
given in Table 43. Address auto-increment is possible in
SPI mode
Table 43. SPI COMMAND WORDS

READ
90h (1001 0000)
91h (1001 0001)
Write Operation
Figures 20 and 21 show the timing diagrams for a write
operation to the ADT7316/7317/7318. Data is clocked
into the registers on the rising edge of SCLK. When the
line is high the DIN and DOUT lines are in three-
state mode. Only when the
does the part accept any data on the DIN line. In SPI
mode the Address Pointer Register is capable of auto-
incrementing to the next register in the register map with-
out having to load the Address Pointer register each time.
In Figure 20 the register address portion of the diagram
gives the first register that will be written to. Subsequent
data bytes will be written into sequential writable registers.
Thus after each data byte has been written into a register,
the Address Pointer Register auto increments it
’
s value to
the next available register. The Address Pointer Register
will auto-increment from 00h to 3Fh and will loop back
to start all over again at 00h when it reaches 3Fh.
Read Operation
Figures 22 and 23 show the timing diagrams necessary to
accomplish correct read operations. To read back from a
register you first have to write to the Address Pointer Reg-
ister with the address of the register you wish to read
from. This operation is shown in Figure 21. Figure 22
shows the procedure for reading back a single byte of data.
The read command is first sent to the part during the first
8 clock cycles, during the following 8 clock cycles the
data contained in the register selected by the Address
Pointer register is outputted onto the DOUT line. Data is
outputted onto the DOUT line on the falling edge of
SCLK. Figure 23 shows the procedure when reading data
from two sequential registers. Multiple data reads are
possible in SPI interface mode as the Address Pointer
Register is auto-incremental. The Address Pointer Regis-
ter will auto-increment from 00h to 3Fh and will loop
back to start all over again at 00h when it reaches 3Fh.

SMBUS/SPI INTERRUPT
The ADT7316/17/18 INTERRUPT output is an interrupt
line for devices that want to trade their ability to master
for an extra pin. The ADT7316/17/18 is a slave only de-
vice and uses the SMBus/SPI INTERRUPT to signal the
host device that it wants to talk. The SMBus/SPI INTER-
RUPT on the ADT7316/17/18 is used as an over/under
limit indicator.
The INTERRUPT pin has an open-drain configuration
which allows the outputs of several devices to be wired-
AND together when the INTERRUPT pin is active low.
Use D6 of the Control Configuration 1 Register to set the
active polarity of the INTERRUPT output. The power-up
default is active low. The INTERRUPT function can be
disabled or enabled by setting D5 of Control Configura-
tion 1 Register to a 1 or 0 respectively.
The INTERRUPT output becomes active when either the
Internal Temperature Value, the External Temperature
Value or the V
DD
Value exceed the values in their corre-
sponding T
HIGH
/V
HIGH
or T
LOW
/V
LOW
Registers. The IN-
TERRUPT output goes inactive again when a conversion
result has the measured value back within the trip limits.
The INTERRUPT output requires an external pull-up
resistor. This can be connected to a voltage different from
V
DD
provided the maximum voltage rating of the INTER-
RUPT output pin is not exceeded. The value of the pull-
up resistor depends on the application, but should be as
large enough to avoid excessive sink currents at the IN-
TERRUPT output, which can heat the chip and affect the
temperature reading.
