2. Functional Description
When it is used in microcomputer systems, the DLC manages the serial communications interface by controlling
the transfer of Bit Oriented Protocol (BOP) serial data in full-duplex communications.
At receiving, it compares the addresses in the HDLC frame input from the communications line, checks the
Frame Check Sequence (FCS), and deletes 0s in frames.
If the addresses match, the DLC receives the frame, in which case the address is accepted as part of the received
data. If the addresses do not match, the DLC ignores the frame.
When CRC is enabled, the DLC checks the FCS in the received frame and indicates the results in the status
register. In this case, the FCS data is not accepted as part of the received data. When CRC is disabled, the
DLC does not check the FCS, but handles it as part of the received data.
At transmitting, the DLC sends the flag pattern, generates and adds the FCS, and inserts 0s in the frame.
Addresses are not sent automatically .
