4.1.1.4
Characteristics: no address recognition
No address recognition is performed and each complete frame will be stored in the SCC
receive FIFO.
4.1.2
The following figures give an overview about the management of the received frames in
the different HDLC operating modes. The graphics show the actual HDLC frame and
how SEROCCO-D interprets the incoming octets. Below that it is shown which octets are
stored in the RFIFO and will thus be transferred into memory.
