eZ80Acclaim! MDS Adapter Board
eZ80F91 Mini Enet Module Interface
UM017001-0404
This section describes functions of the eZ80Acclaim! MDS adapter
board.
The eZ80F91 Mini Enet Module interface on the eZ80Acclaim! MDS
adapter board consists of two 56-pin mini-module receptacles.
Almost all of these receptacles’ signals are connected directly to the CPU.
Three input signals offer options to the application developer by disabling
certain functions of the eZ80F91 Mini Enet Module.
These three input signals are:

A description of these three signals follows.
