The SPI frame can be shortened to only send commands and receive responses if the ADCs are disabled and no ADC data are being output by the device. Read out all expected output data words from each sample period if the ADCs are enabled. Reading all of the data output with each frame provides predictable DRDY pin behavior. If reading out all the data on each output data period is not feasible, see the Section 8.5.4 section on how to begin reading data again after a pause from when the ADCs were last enabled.
A short frame is not possible when using the RESET command. A full frame must be provided for a device reset to take place when sending the RESET command.
