The Flash Row Select Register is a 3-bit value used to define one of the 8 rows of Flash
on a single page. This register is used for all I/O access to Flash memory. In addition,
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).
