There will be no DR pulses if DRMODE<1:0>=00 when
either one or both of the ADCs are in reset or shutdown.
In Mode 00, a DR pulse only happens when both ADCs
are ready. Any DR pulse will correspond to one data on
both ADCs. The two ADCs are linked together and act
as if there was only on channel with the combined data
of both ADCs. This mode is very practical when both
ADC channel data retrieval and processing need to be
synchronized, as in power metering applications.

Note:
DR PULSES WITH SHUTDOWN OR
RESET CONDITIONS
If DRMODE<1:0>=11, the user will still be
able to retrieve the DR pulse for the ADC
not in shutdown or reset, i.e. only 1 ADC
channel needs to be awake.
