Hi Joe,
See the note below that table: E = 1/SYSCLK7 which is the CPU/6 clock that runs the EMIF16 module.
Typically you should be able to find the read/write cycle times and component setup/hold times for your memory device in its datasheet and calculate the components to program accordingly.
For a good example on how this is done, please see the Appendix section (A.2.2.1) of this document: http://www.ti.com/lit/ug/sprufl6f/sprufl6f.pdf
Although it is a different TI device, it uses the same async controller as the 6655/57. You may find it useful and we will try to include that in our 6655/57 collateral.
