ADuC7039
The fast temperature option cannot be used on the first con-
version after ADC power-on. It can only be set after at least
the first ADC interrupt. Waiting for a valid ADC result is
not necessary. Also, a restriction when using the fast tempera-
ture mode is to ensure that SF >=1. In addition, a conversion
rate of 1 ms is recommended in this mode of operation. This is
to ensure the fast result occurs simultaneously with the current
channel result.
When changing the ADCs configuration, by writing ADCMDE,
ADC0CON or ADCFLT, the fast temperature bit must also be
cleared to ensure correct operation. This condition is similar to
a first conversion after ADC power-on.

I-ADC DIAGNOSTICS
The ADuC7039 features the capability to detect open-circuit
conditions on the application board. This is accomplished using
the two current sources on IIN+ and IIN−; these are controlled
via ADC0CON[14:13].
Note that these current sources have a tolerance of ±30%.
