Configuration
REGISTER
Bit 7 - BUSY - This bit indicates that the ADC is currently converting. This bit does not cause either
the ALERT or THERM pins to be asserted.
Bit 6 - IHIGH - This bit is set when the Internal Diode channel exceeds its programmed high limit.
When set, this bit will assert the ALERT pin.
Bit 5 - ILOW - This bit is set when the Internal Diode channel drops below its programmed low limit.
When set, this bit will assert the ALERT pin.
Bit 4 - EHIGH - This bit is set when the External Diode channel exceeds its programmed high limit.
When set, this bit will assert the ALERT pin.
Bit 3 - ELOW - This bit is set when the External Diode channel drops below its programmed low limit.
When set, this bit will assert the ALERT pin.
Bit 2 - FAULT - This bit is asserted when a diode fault is detected. When set, this bit will assert the
ALERT pin.
Bit 1 - ETHERM - This bit is set when the External Diode channel exceeds the programmed THERM
limit. When set, this bit will assert the THERM pin. This bit will remain set until the THERM pin is
released at which point it will be automatically cleared.
Bit 0 - ITHERM - This bit is set when the Internal Diode channel exceeds the programmed THERM
limit. When set, this bit will assert the THERM pin. This bit will remain set until the THERM pin is
released at which point it will be automatically cleared.
The Configuration Register controls the basic operation of the device. This register is fully accessible
at either address.
Bit 7 - MASK_ALL - Masks the ALERT pin from asserting.
Bit 6 - RUN / STOP - Controls Active/Standby modes.
Bit 5 - ALERT/COMP - Controls the operation of the ALERT pin.
Bit 2 - RANGE - Configures the measurement range and data format of the temperature channels.
Configuration Register
‘0’ (default) - The ALERT pin is not masked. If any of the appropriate status bits are set the ALERT
pin will be asserted.
‘1’ - The ALERT pin is masked. It will not be asserted for any interrupt condition unless it is
configured as a secondary THERM pin. The Status Register will be updated normally.
‘0’ (default) - The device is in Active mode and converting on all channels.
‘1’ -The device is in Standby mode and not converting.
‘0’ (default) - The ALERT pin acts in interrupt mode as described in
Interrupt
‘1’ - The ALERT pin acts in comparator mode as described in
Comparator
‘0’ (default) - The temperature measurement range is 0°C to +127.875°C and the data format is
binary.
‘1’ -The temperature measurement range is -64°C to +191.875°C and the data format is offset
binary (see
