These modules provide eight asynchronous serial
communication ports from a single PMC carrier slot.
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.
