of a read cycle and that of a write cycle can be specified individually. The number of wait
states can be selected from the following 15 options:
* SRAM or ROM: All CS spaces (CS0 to CS3) can be assigned.
* SDRAM: Either the CS1 or CS2 space can be assigned.
* Page-ROM: Only the CS2 space can be assigned.
* NAND-Flash: It is not required to setup the CS lines. However, when using

The data bus width is selectable from 8 and 16 bits for the respective chip select spaces.
The number of wait states to be inserted into an external bus cycle is determined by the
