The DSCC4 is designed to handle up to 4 serial data ports in various configurations,
depending on the application. It transfers the data between the serial ports and a shared
memory via its 32 bit/33 MHz PCI Bus Interface which can optionally be configured as a
generic 32 bit de-multiplexed bus interface in the case that no PCI bus is applicable.
Figure 2 provides a general overview upon system integration of the DSCC4 in a PCI
bus environment:
