REFERENCE SOURCES
Both the primary and auxiliary ADCs have the option of using
the internal reference voltage or one of two external differential
reference sources. The first external reference is applied to the
VREF+/VREF pins. The second external reference is applied
to the ADC4/EXT_REF2IN+ and ADC5/EXT_REF2IN pins.
By default, each ADC uses the internal 1.2 V reference source.
For details on how to configure the external reference source for
the primary ADC, see the description of the ADC0REF[1:0]
bits in the ADC0 control register, ADC0CON.
For details on how to configure the external reference source for
the auxiliary ADC, see the description of the ADC1REF[2:0]
bits in the ADC1 control register, ADC1CON.
If an external reference source of greater than 1.35 V is needed
for ADC0, the HIGHEXTREF0 bit must be set in ADC0CON.
Similarly, if an external reference source of greater than 1.35 V
is used for ADC1, the HIGHEXTREF1 bit must be set in
ADC1CON.
DIAGNOSTIC CURRENT SOURCES
To detect a connection failure to an external sensor, the ADuC706x
incorporates a 50 μA constant current source on the selected
analog input channels to both the primary and auxiliary ADCs.
The diagnostic current sources for the primary ADC analog
inputs are controlled by the ADC0DIAG[1:0] bits in the
ADC0CON register.
Similarly, the diagnostic current sources for the auxiliary ADC
analog inputs are controlled by the ADC1DIAG[1:0] bits in the
ADC1CON register.
