EIM External Bus Timing
The External Interface Module (EIM) is the interface to devices external to the i.MX1, including
generation of chip-selects for external peripherals and memory. The timing diagram for the EIM is shown
in Figure 5, and Table 12 defines the parameters of signals.

Note:
1. T is the system clock period. (For 96 MHz system clock, T=10.42 ns)
2. CS5 assertion can be controlled by CSA bits. EB assertion also can be programmable by WEA bits in CS5L register.
3. Address becomes valid and RW asserts at the start of write access cycle.
4.The external wait input requirement is eliminated when CS5 is programmed to use internal wait state.
