The following figure gives an example of an interrupt controlled reception sequence, supposed
that a long frame (66 bytes) followed by two short frames (6 bytes each) are received.

DMA Mode
If the RFIFO contains 32 bytes, the HSCX autonomously requests a block data transfer by
DMA activating the DRQR line as long as the start of the 32nd read cycle. This forces the DMA
controller to continuously perform bus cycles till 32 bytes are transferred from the HSCX to the
system memory.
If the RFIFO contains less than 32 bytes (one short frame or the last part of a long frame) the
HSCX requests a block data transfer depending on the contents of the RFIFO according to the
following table:
