interlock mechanism requires that the high byte register always be read prior to reading the low byte
register.
The status register is a read only register that stores the operational status of the part.
Bit 7 indicates that the ADC is busy converting a value. Bits 6 and 5 indicate that the internal
temperature is above or below its high or low limits respectively. Likewise, bits 4 and 3 indicate that
remote temperature is above or below its limits. See
the limits are compared. Bit 2 indicates that an open circuit on the remote diode anode connection has
been detected. Bits 1 and 0 indicate that the remote temperature or the internal temperature has
exceeded their respective THERM limits. If bits 1 or 0 go high the
When the status register is read, bits 2 through 6 will individually clear provided that the error condition
for that bit no longer exists. The
has responded to the SMBALERT# with an alert response address. The
reset if the status register has not been cleared.
The configuration register controls the functionality of the temperature measurements.
