When the MODE.TDFMODE bit is written to one (TDF optimization is enabled), the SMC takes
advantage of the setup period of the next access to optimize the number of wait states cycle to
insert.

controlled by NWE, on Chip Select 0. Chip Select 0 has been programmed with:
NRDHOLD = 4; READMODE = 1 (NRD controlled)
NWESETUP = 3; WRITEMODE = 1 (NWE controlled)
TDFCYCLES = 6; TDFMODE = 1 (optimization enabled).
When optimization is disabled, data float wait states are inserted at the end of the read transfer,
so that the data float period is ended when the second access begins. If the hold period of the
read1 controlling signal overlaps the data float period, no additional data float wait states will be
inserted.
