P a g e 6 Product Description PMC-4U-CACI is part of the PMC Module family of modular I/O components by Dynamic Engineering. The PMC-4U is capable of providing multiple serial protocols both synchronous and asynchronous with a wide range of baud rates. The CACI interface uses an RS-423 driver, an ...

P a g e 7 An EXAR XR16C854 implements the UART interface. This quad UART device is compatible with the industry standard 16550 UART, but is equipped with 128 byte FIFOs, independent Tx and Rx FIFO counters, automatic hardware/software flow control, and many other enhanced features. An 18.432 MHz ...

P a g e 8 There is also a master interrupt enable that can be set to gate the interrupt onto the PCI bus. The interrupt status is still available in a status register even when the master interrupt enable is off. This facilitates polled operation of interrupt conditions. The individual interrup ...

P a g e 9 Theory of Operation The PMC-4U is designed for transferring data from one point to another with a variety of serial protocols. The PMC-4U features a Xilinx FPGA. The FPGA contains the general control and status registers as well as the interface to the quad UART, SCC, and IO drivers and ...
