The Audio In unit autonomously writes samples to memory in mono and stereo 16
and 32-bit per sample formats, as shown in
stored at increasing memory address locations.
The following table illustrates exactly how the Audio Inout block writes data in
memory (byte) locations precisely after the correct endian swapping done at the
adapter depending on the polarity of the big-endian bit in the Global Registers
Module.
