PMC Modules
PMC520
Octal Serial 232
Communication
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.
Features
Eight RS232E ports
64-byte transmit FIFO buffers
64-byte receive FIFO buffers
Programmable baud rate (up to 120Kbps)
Individual handshake lines (RTS, CTS)
on each channel
Line-break and false start-bit detection
Industry-standard software-compatible 16C550
configuration registers
Benefits
High-density design lowers per-port costs and
saves PMC carrier card slots for other functions.
64-byte FIFO buffers minimize CPU interaction for
improved system performance.
Each serial channel provides handshake support to
simplify interfacing with modems.
Specifications
RS232E Serial Ports
Configuration: Independent, non-isolated serial ports with a
common single return connection and configured as a

buffered, mode selectable.
Interrupts: Receiver line status (overrun, parity, framing error,
or break interrupt); received data available
(FIFO level reached) or character time-out; transmitter
(FIFO level reached); or modem status (CTS).
