2 32 byte FIFO buffers are also provided in receive direction for each HDLC channel.
There are different interrupt indications concerned with the reception of data:
• RPF (RPF2, RPF3, receive pool full) interrupt, indicating that a 32-byte block of data
• RME (RME2, RME3, receive message end) interrupt, indicating that the reception of
The following figure gives an example of a reception sequence, assuming that a “long”
frame (66 bytes) followed by two short frames (6 bytes each) are received.

controller automatically processes the HDLC protocol. Enabling is done by setting of
bit CCR1.EITS and resetting of registers TTR(4:1), RTR(4:1) and FMR1.ENSA.
