Note:

1. FS-S devices are user configurable to have either a hybrid sector architecture (with eight 4-kB sectors and all remaining sectors are

uniform 64 kB or 256 kB) or a uniform sector architecture with all sectors uniform 64 kB or 256 kB. FS-S devices are also user

configurable to have the 4-kB parameter sectors at the top of memory address space. The CFI geometry information of the above table is

relevant only to the initial delivery state. All devices are initially shipped from Spansion with the hybrid sector architecture with the 4-kB

sectors located at the bottom of the array address map. However, the device configuration TBPARM bit CR1NV[2] may be programed to

invert the sector map to place the 4-kB sectors at the top of the array address map. The 20h_NV bit (CR3NV[3} may be programmed to

remove the 4-kB sectors from the address map. The flash device driver software must examine the TBPARM and 20h_NV bits to

determine if the sector map was inverted or hybrid sectors removed at a later time.
