4.2 Non-PCI Host Interface Support
The S5U13506B00C is specifically designed to support a standard PCI bus environment
(using the PCI Bridge Adapter FPGA). However, the S5U13506B00C can directly support
many other Host Bus Interfaces. When the FPGA is disabled (using jumper JP9), headers
H1 and H2 provide the necessary IO pins to interface to the Host Bus Interfaces listed in
Table 4-4:, “CPU Interface Pin Mapping”. The S1D13506 power supply must be set to
3.3V or 5V (using jumper JP1) according to the host CPU signalling voltage.
4.2.1 CPU Interface Pin Mapping
The functions of the S1D13506 host interface pins are mapped to each host bus interface
according to the following table.
