1.0 Functional Description
(Continued)
1.12 Fault Queue
In order to suppress erroneous ALERT or T_CRIT triggering
the LM86 incorporates a Fault Queue. The Fault Queue acts
to insure a remote temperature measurement is genuinely
beyond a HIGH, LOW or T_CRIT setpoint by not triggering
until three consecutive out of limit measurements have been
made, see
Figure 10
. The fault queue defaults off upon
power-up and may be activated by setting bit D0 in the
Configuration register (09h) to “1”.
1.13 One-Shot Register
The One-Shot register is used to initiate a single conversion
and comparison cycle when the device is in standby mode,
after which the device returns to standby. This is not a data
register and it is the write operation that causes the one-shot
conversion. The data written to this address is irrelevant and
is not stored. A zero will always be read from this register.
2.0 LM86 REGISTERS
2.1 COMMAND REGISTER
Selects which registers will be read from or written to. Data for this register should be transmitted during the Command Byte of
the SMBus write communication.
