IMPORTANT: The following describes the Data Pattern setup: Addresses [0x0-0xFFFFF] is Flash. Addresses [0x40C] is Flash security byte(FSEC). There are two security bits(bit 0 and bit 1) and two mass erase bits(bit 4 and bit 5) in FSEC. When mass erase is disabled(bit 4=0′ bit 5=’1′) and device secured the device is no longer erase. Addresss [0x40D] is Flash Nonvolatile Option Byte(FOPT). There is EZPORT_DIS bit(bit 1) in FOPT Register. After programmed this bit to ‘0’ the Ezport operation is disabled. If the Ezport operation is disabled the read operation will read all FF. The algorithm supports the 32 bit long word in Big-Endian byte order. Please make sure that the data file is also in such byte order. ‘
