ExpressCard-Mode operation

Figure 1-9. EVM Configuration for ExpressCard Mode

To configure the XIO3130 EVM for ExpressCard-mode operation, the six jumpers (J7, J11, J13, J14, J15, J16) must be populated (see Figure 1-5). This routes power directly to slots 1 and 2 bypassing the TPS2363, which is not required for ExpressCard operation.

The dipswitch should be configured with SCL, DN1_DPSTRP, DN2_DPSTRP, and DN3_DPSTRP slide switches all in the up position. This configuration enables the EEPROM and enables ExpressCard operation on all three slots. To use two of the PCIe slots in normal-mode operation and one slot for ExpressCard operation, two of the DNx_DPSTRP slide switches must be in the down position and the EEPROM needs to be programmed correctly to support this mode of operation. By default, the ExpressCard mode EEPROM .dat file is set up to enable ExpressCard-mode operation in any of the PCIe slots that disables the other non-ExpressCard slots from operating in normal mode.
