It looks like Size Bit_1 was re-purposed to select TOP or BOTTOM FRAM, but the FRAM USED column doesn't match Size Bit_1. The table should probably look like this:



The highlighted cells indicate invalid 16K/TOP configurations.

Note 1: These would be the 32K/TOP configurations. Only 32K F_Blocks can be swapped between the TOP and BOTTOM. See 6).
Note 2: These would be the 16K/BOTTOM configurations.

Note that 8 and C are also invalid as 16K blocks can only be LCIM. If BOTTOM = 1 then we gain configuration options 2 and 6 and lose 4.
