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.
