Hardware Differences

The FDM had no capability of supplying the target power whereas the E8Direct can supply 3.3V or 5V and
the FDM-E8Direct pin usage is different. This means that it is not possible to simply swap an FDM for an
E8. The general purpose I/O pins on the FDM were labelled as MD0 to MD4 and FWE, and they had a
direct mapping with the mode pins with matching names on the target devices. Because the number of
available general purpose I/O pins is reduced on the E8, and the locations on the 14-pin header are
different, we can no longer have a direct mapping between device mode pin names and E8 I/O pins, so we
have chosen to label them as 'A', 'B', 'C' and 'D'. The pin settings required for E8Direct will have to be
board specific rather than device specific.
