Status Byte Functions
The status byte register (Table 7) indicates which (if
any) temperature thresholds have been exceeded. This
byte also indicates whether the ADC is converting and
whether there is an open circuit in the remote-diode
DXPDXN path. After POR, the normal state of all the
flag bits is zero, assuming none of the alarm conditions
are present. The status byte is cleared by any success-
ful read of the status byte, unless the fault persists.
Note that the ALERT interrupt latch is not automatically
cleared when the status flag bit indicating the ALERT is
cleared. The fault condition must be eliminated before
the ALERT can be cleared.
When reading the status byte, check for internal bus
collisions caused by asynchronous ADC timing, or else
disable the ADC prior to reading the status byte
(through the RUN/STOP bit in the configuration byte). In
one-shot mode, read the status byte only after the con-
version is complete, which is 150ms max after the one-
shot conversion is commanded.
