The WAKEUP command brings the ADC out of standby mode. The ADC channels must be enabled by writing to the ADC_ENA register before bringing the device out of standby mode. Allow enough time for all circuits in standby mode to power-up (see the Electrical Characteristics table for details). The command status response following a WAKEUP command is 0033h. An example showing the response to exiting standby mode using the WAKEUP command is shown in Figure 71.
