Specifications
3.9 External Interface Module
The External Interface Module (EIM) handles the interface to devices external to the MC9328MX1, including
generation of chip-selects for external peripherals and memory. The timing diagram for the EIM is shown in
Figure 5, and Table 13 defines the parameters of signals.
