LIMIT AND STATUS REGISTERS
LIMIT VALUES
Associated with each measurement channel on the ADT7470
are high and low limits. These can form the basis of system
status monitoring; a status bit can be set for any out-of-limit
condition and be detected by polling the device. Alternatively,
SMBALERT interrupts can be generated to automatically flag
a service processor or microcontroller for out-of-limit
conditions as they occur.
TEMPERATURE LIMITS
Table 9 lists the 8-bit temperature limits on the ADT7470.

FAN SPEED LIMITS
The fan tach measurements are 16-bit results. The fan tach
limits are also 16 bits, consisting of two bytes: a high byte and
low byte. On the ADT7470 it is possible to set both high and
low speed fan limits for over speed and under speed or stall con-
ditions. Be aware that, because the fan tach period is actually
being measured, exceeding the limit by 1 indicates a slow or
stalled fan. Likewise, exceeding the high speed limit by 1
generates an over speed condition.

OUT-OF-LIMIT COMPARISONS
Once all limits are programmed, the ADT7470 can be enabled
to begin monitoring. The ADT7470 measures all parameters in
round-robin format and sets the appropriate status bit for out-
of-limit conditions.
Comparisons are done differently depending on whether the
measured value is compared to a high limit or a low limit.
High Limit: > Comparison Performed
Low Limit: ≤ Comparison Performed
