There is some doc here on the feature: https://www.mathworks.com/help/supportpkg/plutoradio/ug/burst-mode.html

Bascially what it does internally is set the number of kernel buffers (https://codedocs.xyz/analogdevicesinc/libiio/group__Device.html#gabda6d5a2ce3500204a022702c3c925fe) to 1. This will make successive buffers discontiguous but you can capture the largest possible contiguous buffer. This is from the device itself.

The FramesInBurst setting will split that received buffer into smaller vectors on the host side to something you want. So once you step through those FramesInBurst the next buffer is discontiguous, but the next FramesInBurst buffers will be contiguous.

When not in burst mode the system is more elastic since there are several buffers used in the hardware. 4 by default. As long as you can pull data from these buffers fast enough you can contiuously stream without dropping samples. However, if you overflow then it can be difficult to determine which buffers are discontiguous since these reports are not synchronized with the buffers themselves in MATLAB.
