This leads to the following address configuration:
In the receive direction, blocks are swapped in two cases:
• The receive buffer is full. The swap is issued immediately after the buffer has become
• An end of a frame indication was detected at the beginning of a frame. The frame is
In the transmit direction blocks are swapped each time a start transmission command is
issued in the command register.

case of a buffer full indication followed by an end of frame indication, this condition
becomes true only if additionally there was no FULL interrupt during the previous
frame.
