Figure 17. Typical SPI Interface Connection
The ADT7310 has a 4-wire serial peripheral interface (SPI). The
interface has a data input pin (DIN) for inputting data to the
device, a data output pin (DOUT) for reading data back from
the device, and a data clock pin (SCLK) for clocking data into
and out of the device. A chip select pin (CS
) enables or disables
the serial interface. CS
is required for correct operation of the
interface. Data is clocked out of the ADT7310 on the negative
edge of SCLK, and data is clocked into the device on the
positive edge of SCLK.
SPI COMMAND BYTE
All data transactions on the bus begin with the master taking
CS
from high to low and sending out the command byte. This
indicates to the ADT7310 whether the transaction is a read or
a write and provides the address of the register for the data
transfer. Table 15 shows the command byte.

Bit C7 of the command byte must be set to 0 to successfully
begin a bus transaction. The SPI interface does not work
correctly if a 1 is written into this bit.
Bit C6 is the read/write bit; 1 indicates a read, and 0 indicates
a write.
Bits[C5:C3] contain the target register address. One register can
be read from or written to per bus transaction.
Bit C2 activates a continuous read mode on the temperature
value register only. When this bit is set, the serial interface is
configured so that the temperature value register can be
continuously read. When the command word is 01010100
(0x54), the contents of the temperature value register can be
read out without requiring repeated writes to set the address
bits. Simply sending 16 SCLK clocks to the ADT7310 clocks the
contents of the temperature value register onto the DOUT pin.
