PC/104 ISA card access (cpld_isa)

Compatibility Eagle 100

A complex programmable logic device is a programmable logic device with complexity between that of PALs and FPGAs, and architectural features of both. The building block of a CPLD is the macro cell, which contains logic implementing disjunctive normal form expressions and more specialized logic operations.

PC/104 is an embedded computer standard controlled by the PC/104 Consortium which defines both a form factor and computer bus. PC/104 is intended for specialized embedded computing environments where applications depend on reliable data acquisition despite an often extreme environment.

This example tests ISA (PC/104) card on CPLD.
