3.8 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.
