The reception of monitor messages may also (if required) be aborted at any time simply
by setting the CMDR_E:MFFR bit while the receive transfer is still in operation.
If more than 16 bytes shall be received, the following procedure can be adopted:
The first 16 data bytes received will be stored in the MFFIFO and acknowledged to the
remote partner. The presence of a 17
ISTA_E:MFFI interrupt. While the transfer is still in operation (STAR_E = 16
