General Description

The R68560, R68561 Multi-Protocol Communications Controller (MPCC) interfaces a single serial communications channel to a 68008/68000 microcomputer-based system using either asynchronous or synchronous protocol.

High speed bit rate, automatic formatting, low overhead programming, eight character buffering, two channel DMA interface and three separate interrupt vector numbers optimize MPCC performance to take full advantage of the 68008/68000 processing capabilities and asynchronous bus structure.

In synchronous operation, the MPCC supports bit-oriented protocols (BOP), such as SDLC/HDLC, and character-oriented protocols (COP), such as IBM Bisync (BSC) in either ASCII or EBCDIC coding.
