face requires that the eZ80L92 Module also be mounted on the eZ80
Development Platform, because it (the eZ80L92 Module) contains the
eZ80L92 microprocessor. To mount an application module, use the two
male headers J6 and J8.
Jumper J6 carries the general-purpose port, and jumper J8 carries mem-
ory and control signals. To design an application module, the user should
be familiar with the architecture and features of the eZ80L92 Module cur-
rently installed. Tables 4 and 5 list the signals and functions related to
each of these jumpers by pin. Power and ground signals are omitted for
the sake of simplicity.
