3.19 External Interface Module (EIM)
The External Interface Module (EIM) handles the interface to devices external to the i.MX21, including
generation of chip-selects for external peripherals and memory. The timing diagram for the EIM is shown
in Figure 53, and Table 41 on page 68 defines the parameters of signals.
