still exists, they are reasserted at the end of the next
conversion. If the MAX6680/MAX6681 are operating in
the comparator mode, bits 26 of the Status register
are cleared only after the local and/or remote tempera-
tures return within the set limits.
The bits indicating OVTI and OVTE are cleared only
when the condition no longer exists. Reading the status
byte does not clear the OVERT output or fault bits. One
way to eliminate the fault condition is for the measured
temperature to drop below the temperature threshold
minus the hysteresis value. Another way to eliminate
the fault condition is by writing new values for the
RWOI, RWOE, or HYST registers so that a fault condi-
tion is no longer present.
The MAX6680/MAX6681 incorporate collision avoid-
ance so that completely asynchronous operation is
allowed between SMBus operations and temperature
conversions.
When autoconverting, if the T
HIGH
and T
LOW
limits are
close together, it is possible for both high-temp and
low-temp status bits to be set, depending on the
amount of time between status read operations. In
these circumstances, it is best not to rely on the status
bits to indicate reversals in long-term temperature
changes. Instead use a current temperature reading to
establish the trend direction.
Hardware/Software Reset
The MAX6680/MAX6681 reset at power-on if pin 7 is
taken high, or by software reset through bit 1 of the
Configuration register. When reset occurs, all registers
go to default values, and the SMBus address pins are
sampled.

time interval between conversions in free-running
