Reception and Transmission Functions
FIFO Structure
Each HDLC controller uses a 64-byte FIFO per direction for the intermediate storage of data
packets. All data bytes between the opening flag and the CRC field of an HDLC frame are passed
through the FIFO.

HDLC Frame Structure
The receive and transmit FlFOs are both divided, two blocks of 32 bytes each: One accessible to
the microcontroller and one inaccessible to the microcontroller. While the microcontroller is reading
(receive FIFO) or writing (transmit FIFO) data in one 32-byte block, the other block is filled (receive
FIFO) or emptied (transmit FIFO) by the IDEC. Thus the length of the received or transmitted frame
is not limited by the FIFO size.
