    192192For the FF400, the buffer is written in 32-quadlet (128-byte) sub-blocks via 
    193 a bounce buffer.  If the final sub-block is not 32-quadlets the write is only 
    194 as big as the sub-block (that is, no padding takes place).  The sub-block 
    195 data to be written is sent to register 0x80100290.  The 2-quadlet register 
    196 at 0x80100288 is set with the flash address to write the block to and the 
    197 size (in bytes) of the data block.  Finally, a 0x1 is written to CBA+(8*4) 
    198 to initiate the write.  Polling for "device not busy" should commence after 
    199 a wait of 2 ms.

    208208On the FF400, erasure is controlled by writing a special magic number to 
    209 the the flash erase control register (CBA+8*4):
