The DS33Z11 will encode the MAC Frame with the LAPS encapsulation on a complete serial stream if configured
for X.86 mode in the register LI.TX86E. The DS33Z11 provides the following functions:
Control Registers for Address, SAPI, Destination Address, Source Address
32 bit FCS enabled
Programmable X
43+1 scrambling
The sequence of processing performed by the receiver is as follows:
Programmable octets X
43+1 descrambling
Detect the Start Flag (7E)
Remove Rate adaptation octets 7D, DD.
Perform transparency-processing 7D, 5E is converted to 7E and 7D, 5D is converted to 7D.
Check for a valid Address, Control and SAPI fields (LI.TRX86A to LI.TRX86SAPIL)
Perform FCS checking
Detect the closing flag.
