Flash Data Register
The Flash Data register stores the data values to be programmed into Flash memory via
I/O Write operations. An I/O read of the Flash Data register returns data from Flash
memory. The Flash memory address used for I/O access is determined by the contents of
the page, row, and column registers. Each access to the FLASH_DATA register causes an
autoincrement of the Flash address stored in the Flash Address registers (FLASH_PAGE,
FLASH_ROW, FLASH_COL). See
