4.5 PC/104-Bus

An onboard LPC-to-ISA bridge (Fintek® F85226F) makes it possible to expand the functionality of the

board with additional PC/104 cards. This interface offers full 16bit ISA compliance. For further information

on this interface please refer to the PC/104 specifications (see "Specifications and Documents", p. 12).
