Data Sheet

CONTINUOUS READ MODE
When the command byte = 01010100 (0x54), the contents of
the temperature value register can be read out without requiring
repeated writes to the communications register. By sending 16
SCLK clocks to the ADT7310, the contents of the temperature
value register are output onto the DOUT pin.
To exit the continuous read mode, the Command Byte
01010000 (0x50) must be written to the ADT7310.
While in continuous read mode, the part monitors activity on
the DIN line so that it can receive the instruction to exit the
continuous read mode. Additionally, a reset occurs if 32
consecutive 1s are seen on the DIN pin. Therefore, hold DIN
low in continuous read mode until an instruction is to be
written to the device.
In continuous read mode, the temperature value register cannot
be read when a conversion is taking place. If an attempt is made
to read the temperature value register while a conversion is
taking place, then all 0s are read. This is because the continuous
read mode blocks read access to temperature value register
during a conversion.
SHUTDOWN
The ADT7310 can be placed in shutdown mode by writing 1
to Bit 6 and 1 to Bit 5 of the configuration register (Register
Address 0x01). The ADT7310 can be taken out of shutdown
mode by writing 0 to Bit 6 and 0 to Bit 5 of the configuration
register (Register Address 0x01). The ADT7310 typically takes
1 ms (with a 0.1 礔 decoupling capacitor) to come out of shut-
down mode. The conversion result from the last conversion
prior to shutdown can still be read from the ADT7310 even
when it is in shutdown mode. When the part is taken out of
shutdown mode, the internal clock is started and a conversion
is initiated.
FAULT QUEUE
Bit 0 and Bit 1 of the configuration register (Register Address
0x01) are used to set up a fault queue. Up to four faults are
provided to prevent false tripping of the INT and CT pins
when the ADT7310 is used in a noisy temperature environ-
ment. The number of faults set in the queue must occur
consecutively to set the INT and CT outputs. For example,
if the number of faults set in the queue is four, then four
consecutive temperature conversions must occur, with each
result exceeding a temperature limit in any of the limit registers,
before the INT and CT pins are activated. If two consecutive
temperature conversions exceed a temperature limit and the
third conversion does not, the fault count is reset to zero.
