Functional Description and Application Information

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 can also 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.
