Freescale Semiconductor
Note:
1. T is the system clock period. (For 96 MHz system clock, T=10.42 ns)
2. OE and EB assertion time is programmable by OEA bit in CS5L register. EB assertion in read cycle will occur only when
EBC bit in CS5L register is clear.
3. Address becomes valid and CS asserts at the start of read access cycle.
4. The external wait input requirement is eliminated when CS5 is programmed to use internal wait state.
