Field
Mnemonic
FMC_MID Manufacturer's Identifier (FFFF = Undefined/Not-
Applicable)
FMC_DID Manufacturer's Device Identifier (FFFF =
Undefined/Not-Applicable)
FMC_DDW Device Data Width (e.g., 8-bits, 16-bits)
FMC_NOD Number of Devices/Sockets Present
FMC_NOC Number of Columns (Interleaves)
FMC_CW Column Width in Bits
This will always be a multiple of the device's data
width.
FMC_WEDW Write/Erase Data Width
The FLASH memory devices must be programmed in
parallel when the write/erase data width exceeds the
device's data width.
FMC_BANK Bank Number of FLASH Memory Array: 0 = A, 1 = B
FMC_SPEED ROM Access Speed in Nanoseconds
FMC_SIZE Total Bank Size (Should agree with the physical
organization above): 00=256K, 01=512K, 02=1M,
03=2M, 04=4M, 05=8M
