REGISTER
The Configuration 2 Register controls the basic functionality of the EMC1053 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.
Bit 2 - DA_n - controls the dynamic digital averaging circuitry. See
Bit 1 - COMP - configures the device to perform a comparison for the Hotter of Two mode (see
3.3, "Operation During Run Mode," on page
Configuration 2 Register - (04h)
‘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.
‘0’ (default) - dynamic averaging is enabled. Depending on the selected conversion rate, the ADC
averaging factor is increased for the external diodes.
‘1’ - dynamic averaging is disabled. The ADC averaging factor will remain fixed at 1x for all
conversion rates and will allow increased power savings at the slower conversion rates.
‘0’ (default) - the device is in normal mode
‘1’ - the device is in Hotter of Two mode. In this mode, the two external diode channels are
measured and compared against each other. The hotter of the two channels has its data loaded
