8 asynchronous full duplex EIA/TIA-422B serial ports (supports EIA-485)
64-byte FIFO buffers
Interrupt support
Programmable baud rate (up to 1.8432Mbps)
These modules provide eight asynchronous serial communication ports from a single PMC Socket. Software-configurati
on helps you quickly set baud rates, character-sizes, stop bits, and parity.
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, data set, and flow control interrupts. A global interrupt source register provides interrupt status indication for all eight channels to speed up interrrupt parsing.
