CMOS dual universal serial communications controller

(CDUSCC)

1998 Sep 04

• Odd or even parity, no parity, or force parity

• Up to two stop bits programmable in 1/16-bit increments

• 1X or 16X Rx and Tx clock factors

• Parity, overrun and framing error detection

• False start bit detection

• Break generation with handshake for counting break characters

• Detection of start and end of received break

• Character compare with optional interrupt on match

• Transmit and receive up to 10Mbps at 1x or 1Mbps at 16x data

rates

Bit-Oriented Protocol

• Character length: 5 to 8 bits

• Detection and transmission of residual character: 0–7 bits

• Automatic switch to programmed character length for I field

• Zero insertion and deletion

• Optional opening PAD transmission

• Detection and generation of FLAG, ABORT, and IDLE bit patterns

• Transmit 7 or 8 bit ABORT

• Detection and generation of shared (single) FLAG between

frames

• Detection of overlapping (shared zero) FLAGs

• Idle in MARK or FLAGs

• Secondary address recognition including group and global

address

• Single- or dual-octet secondary address

• Extended address and control fields

• Short frame rejection for receiver

• Detection and notification of received end of message

• CRC generation and checking

• SDLC loop mode capability

Character-Oriented Protocols

• Character length: 5 to 8 bits

• Odd or even parity, no parity, or force parity

• LRC or CRC generation and checking

• Optional opening PAD transmission

• One or two SYN characters

• External sync capability

• SYN detection and optional stripping

• SYN or MARK line-fill or underrun

• Idle in MARK or SYNs

• Parity, FCS, overrun and underrun error detection

• Optional SYNC exclusion from FCS

• BISYNC features

– EBCDIC or ASCII header, text and control messages

– SYN, DLE stripping

– EOM (end of message) detection and transmission

– Auto transparency mode switching

– Auto hunt after receipt of EOM sequence (with closing PAD

check after EOT or NAK)

– Control character sequence detection for both transparent and

normal text

– Parity generation for data and LRC characters
