9 SCC General Information
The Serial Communications Controller (SCC) is a dual channel, multi-protocol data
communications peripheral. The MPAP-100 provides a single channel for communications,
however, portions of the second channel can be utilized to support some special circumstances.
The SCC can be configured to satisfy a wide variety of serial communications applications.
Some of its protocol capabilities include:
SDLC/HDLC (Bit Synchronous) Communications
Abort sequence generation and checking
Automatic zero insertion and deletion
Automatic flag insertion between messages
Address field recognition
I-field residue handling
CRC generation and detection
SDLC loop mode with EOP recognition/loop entry and exit
Byte-oriented Synchronous Communications
Internal/external character synchronization
1 or 2 sync characters in separate registers
Automatic Cyclic Redundancy Check (CRC) generation/detection
Asynchronous Communications
5, 6, 7, or 8 bits per character
1, 1-1/2, or 2 stop bits
Odd, even, or no parity
Times 1, 16, 32, or 64 x clock modes
Break generation and detection
Parity, overrun and framing error detection
NRZ, NRZI, or FM encoding/decoding
