In burst mode, the output data is alternated between a high-resolution, 12-bit output of 2^N samples and a low-resolution, 7-bit or 11-bit output of 2^N+3 samples. Burst mode is enabled through a SPI register write and there are two basic operating modes available: a manual trigger mode where the high-resolution output is initiated through an external trigger and an auto-trigger mode where the internal logic transitions to a high-resolution output immediately after transmitting the last low-resolution sample. After burst mode is enabled through a SPI register write, the ADS54T01 transmits 2¹³ low-resolution samples and the trigger command is locked out until completion.

The parameter N can be changed through the SPI at any time. The change will go into effect with the next output cycle, starting with the transmission of low-resolution samples. The default value for N after reset is N=10.
