HDLC CONTROLLERS

HDLC DATA ENCODING/DECODING  
Data encoding is utilized to allow the transmission of clock and data information over the same medium. This  
saves the need to transmit clocks and data over a separate medium as would normally be required for  
synchronous data. The HDLC provides four different data encoding methods, selected by bits in HCON1[18:16].  
An example of these four encoding methods is shown in figure 8-5.
