Hardware and Software Design • Manufacturing Services 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.
Hardware and Software Design • Manufacturing Services 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.
Hardware and Software Design • Manufacturing Services 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.
Hardware and Software Design • Manufacturing Services 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.

Hardware and Software Design • Manufacturing Services P a g e 1 2 Programming Programming the PMC-4U requires only the ability to read and write data from the host. The base address is determined by the PMC Carrier board. The base address refers to the first user address for the slot in which the PMC is installed.

Hardware and Software Design • Manufacturing Services P a g e 1 7 PMC4U_SCC_IVEC [0X0C] PMC-4U SCC Interrupt Acknowledge/Vector Read A read from this address causes the SCC interrupt acknowledge signal to be asserted. If an interrupt condition exists in the SCC, it will respond by placing an interrupt vector on the local data bus.
Hardware and Software Design • Manufacturing Services P a g e 1 8 Parallel termination resistors are supplied on each differential pair along with a switch to allow the user to select which lines are terminated and where.
Hardware and Software Design • Manufacturing Services P a g e 1 9 PMC4U_SCC_A_CNTL [0X18] PMC-4U SCC Channel A Control Register read/write This address is used to access all of the channel A registers. In order to access a register other than this base register, the register number is first written to this address.
Hardware and Software Design • Manufacturing Services P a g e 2 0 PMC4U_UART_A [0X40] PMC-4U UART A Base Address This is the base address for the eight register addresses associated with UART A. Figure 3 gives an overview of these registers and their functions.
