If page mode is enabled, this field indicates the size of the page in bytes.

1: Asynchronous burst read in page mode is applied on the corresponding chip select.

0: Standard read is applied.

1: TDF optimization is enabled. The number of TDF wait states is optimized using the setup period of the next read/write 

access.

0: TDF optimization is disabled.The number of TDF wait states is inserted before the next access begins.

This field gives the integer number of clock cycles required by the external device to release the data after the rising edge of the 

read controlling signal. The SMC always provide one full cycle of bus turnaround after the TDFCYCLES period. The external 

bus cannot be used by another chip select during TDFCYCLES plus one cycles. From 0 up to 15 TDFCYCLES can be set.
