If the StrataFlash memory is in byte-wide (x8) mode (SF_BYTE = Low), the FPGA
application has full simultaneous read/write access to both the LCD and the StrataFlash
memory. In byte-wide mode, the StrataFlash memory does not use the SF_D<15:8> data
lines.

The 2 x 16 character LCD has an internal Sitronix
functionally equivalent with the following devices.

The controller has three internal memory regions, each with a specific purpose. The
display must be initialized before accessing any of these memory regions.
The Display Data RAM (DD RAM) stores the character code to be displayed on the screen.
Most applications interact primarily with DD RAM. The character code stored in a DD
RAM location references a specific character bitmap stored either in the predefined
ROM
Figure
upper line of characters is stored between addresses 0x00 and 0x0F. The second line of
characters is stored between addresses 0x40 and 0x4F.
