SPI Component Device ID 1: This identifies the second byte of the Device ID of the
SPI Flash Component. This is the third byte returned by the Read JEDEC-ID command
(opcode 9Fh).
SPI Component Device ID 0: This identifies the first byte of the Device ID of the SPI
Flash Component. This is the second byte returned by the Read JEDEC-ID command
(opcode 9Fh).
SPI Component Vendor ID: This identifies the one byte Vendor ID of the SPI Flash
Component. This is the first byte returned by the Read JEDEC-ID command (opcode
9Fh).
Reserved
Write Enable on Write to Status (WEWS):
0 = No Write Enable (06h) command is required to write to the Status register
1 = Write Enable (06h) is required to the Write Status Register prior to write and erase
NOTE: If there is more than one component, both components must use the same Write
Default
to remove any protection.

VSCC Table Length (VTL): Identifies the 1’s based number of DWORDS
contained in the VSCC Table. Each SPI Component entry in the table is 2
DWORDS long.
VSCC Table Base Address (VTBA): This identifies address bits [11:4] for
the VSCC Table portion of the Flash Descriptor. Bits [24:12] and bits [3:0]
are 0.
