MC68360 USER’S MANUAL
— Supports linked lists of frames for both transmit and receive
— Provides error handling and recovery for both transmit and receive
— Supports all serial ports in different protocol configurations
— Provides internal loopback (frames not sent to QUICC)
Provides timer services
Can be configured to send trace messages to a system log file
Supports up to 24 serial ports
The LAPD module features are as follows:
Fully implements 1988 CCITT Recommendation Q.920/Q.921
Supports up to 12 physical channels (8192 logical links per channel)
Supports management and broadcast links
Supports user and network applications
Uses dedicated transmit pool for fast control frame generation
Dynamic modification of protocol parameters
Independent of layer 1 and layer 3 implementation
Independent of layer 2 management
Message-oriented interface
Independent configuration of upper and lower layer modules interfacing with each
LAPD link
Special mode for internal loopback between pairs of links
Supports external loopback between two QUICC serial channels or on the same serial
channel
Trace option for reporting to system management each primitive issued by the LAPD
module to the layer 3 or layer 2 management
The LAPB module features are as follows:

tion
Modulo 8 or 128 operation
Applicable for DTE and DCE applications
Uses dedicated transmit pool for fast control frame generation
Dynamic modification of protocol parameters
Independent of layer 1 and layer 3 implementation
Message-oriented interface
Independent configuration of upper and lower layer modules interfacing with each
LAPB link
Special mode for internal loopback (frames are not sent to the driver)
