Pin Description
Mini Module Connector J1 – Peripheral Bus
Figure 2 illustrates the pin layout of the 56-pin Peripheral Bus Connector (J1) of the
eZ80F91 Mini Enet Module. The eZ80F91 Mini Enet Module is designed to connect to
your applications via connectors J1 and J2, where the entire system bus and I/O port
signals are available. The module is also compatible with Zilog’s eZ80F91 Modular
Development System (eZ80F910100KIT). Table 1 on page 5 lists the pins and their
functions.
