PMC520:
Serial Communication, 232 Octal
• 8 asynchronous EIA/TIA-232E serial ports
• 64-byte FIFO buffers
• Interrupt support
• Programmable baud rate (up to 120Kbps)
These modules provide eight asynchronous serial communication ports from a single PMC Socket. Software-configuration helps you quickly set baud rates, character-sizes, stop bits, and parity. Signal support for RTS/CTS handshaking is also included.
For more efficient data processing, each serial port is equipped with 64-character FIFO buffers on the transmit and receive lines.
The data ports generate individually controlled transmit, receive, line status, and data set interrupts. A global interrupt source register provides interrupt status indication for all eight channels to speed up interrupt parsing.
