Section 3 Support Information
3.1 Introduction
This section consists of connector pin assignments, connector signal
descriptions, and other information that may be useful in your development
activities. For the ATA and memory card interfaces, signals described as
outputs are signals that originate from the external device. Input signals
originate on the board going to the device.
3.2 Top CompactFlash Connector
Connector J11 is one of two CompactFlash connectors on the EVB912UF32.
This connector shares signals with the ATA connector, J2, so these connectors
cannot be used at the same time. To use a CompactFlash card and the ATA
interface simultaneously, use the bottom CompactFlash connector, J13. Note
that when using J13, W19 should select VDDX as the VDD3X power source.
Figure 3-1 gives pin assignments for the top CF connector, J11. Figure 3-2
gives pin assignments for the bottom CF connector. The signal names match the
names used in the schematic and may not be the signal name normally
associated with CompactFlash. Table 3-1 gives signal descriptions for these
connectors. The signal names on the table might not match the schematic or the
figures. Instead they show the intended CompactFlash function that must be
selected for that particular pin.
