commodore ~ aamiconduct:ar group ~~@~ MPS 6551 ASSYNCH RONOUS COMMUNICATION INTERFACE ADAPTER [ 6551 ASYNCHRONOUS COMMUNICATION INTERFACE ADAPTER CONCEPT: The 6551 is an Asynchronous Communication Adapter (ACIA) intended to provide for interfacing the 6500/6800 microprocessor families to serial communication data sets and modems.
A unique feature is the inclusion of an on-chip programmable baud rate generator, with a crystal being the only external com pone t required.
FEATURES: • On-chip baud rate generator: 15 programmable baud rates derived from a standard 1.
8432 M Hz external crystal (50 to 19,200 baud).
• Programmable interrupt and status register to simplify software design.
• Single +5 volt power supply.
• Serial echo mode.
• False start bit detection.
• 8-bit bi-directional data bus for direct communicati~ ) -standard baud rates (up engths; number of stop bits; and nd detection.
