)

Read from device when converter has the channel sequencer activated. Enter register mode to read/write registers.

Parameters
[in]dev- ad469x_dev device handler.
[out]buf- data buffer.
[in]samples- Number of samples per channel. For example, if with ad469x_std_sequence_ch 2 channel where activated, buf will be filled with 10 samples for each of them. If temp is enable, the there will be an other 10 samples for temperature
Returns
SUCCESS in case of success, FAILURE otherwise.
