DR PULSES WITH SHUTDOWN OR

RESET CONDITIONS

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.

Figure 6-8 represents the behavior of the data ready

pin with the different DRMODE and DR_LTY configura-

tions, while shutdown or resets are applied.

Note:

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.
