R68560 Overview
The R68560, R68561 Multi-Protocol munications Controller (MPCC) interfaces a single serial munications channel to a 68008/68000 microputer-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...
R68560 Key Features
- Full duplex synchronous/asynchronous receiver and transmitter
- Implements IBM Binary Synchronous munications (BSC)
- Supports other synchronous character-oriented protocols
- Supports synchronous bit oriented protocols (BOP), such as
- Asynchronous and isochronous modes
- Modem handshake interface
- High speed serial data rate (DC to 4 MHz)
- Internal oscillator and baud rate generator with programma
- Crystal or TTL level clock input and buffered clock output
- Direct interface to 68008/68000 asynchronous bus
