1°C Triple Temperature Sensor with Hotter of Two Zones
Datasheet
The Configuration Register controls the basic functionality of the EMC1063. The bits are described
below:
Bit 6 - STANDBY- controls the ADC conversions and power modes of the part.
'0' - The device is in the run operating mode. The ADC is converting at the user-programmed
conversion rate.
'1' - (default) The device is in the standby operating mode (see Section 3.1).
Bit 2-0 - CR<2:0> - determines the conversion rate for the temperature monitoring per Table 4.4.

The Configuration 2 Register controls the basic functionality of the EMC1063 that is NOT compatible
with the EMC1023.
Bit 3 - MAX_RES - controls the external diode conversion time during dynamic averaging. Although
the dynamic averaging may be used to increase the ADC resolution, only 11 bits of data are available
in the temperature registers.
‘0’ - the dynamic averaging will set the ADC averaging factor at 1x when the conversion rate is set
at 16 conversions per second and 2x at conversion rates lower than 16 per second.
‘1’ (default) - the dynamic averaging will set the ADC averaging factor at 1x when the conversion
rate is set at 16 conversions per second, 2x at 8 conversions / second and 4x at conversion rates
lower than 8 per second.
Bit 2 - DA_n - controls the dynamic digital averaging circuitry. See Section 3.3.2.
‘0’ (default) - dynamic averaging is enabled. Depending on the selected conversion rate, the ADC
averaging factor is increased for the external diodes.
