For the CompactFlash Storage Cards that do not support security mode feature set, this
command is effectively a NOP command and only implemented for backward compatibility. The Sector Count
Register will always be returned with a 00h indicating Wear Level is not needed. If the CompactFlash Storage Card
supports security mode feature set, this command shall be handled as Security Freeze Lock.
Write Buffer – E8h
Bit->
The Write Buffer command enables the host to overwrite contents of the CompactFlash Storage Card’s sector
buffer with any data pattern desired. This command has the same protocol as the Write Sector(s) command and
transfers 512 bytes.
Write Long Sector –32h or 33h
Bit->
This command is similar to the Write Sector(s) command except that it writes 516 bytes instead of 512 bytes. Only
single sector Write Long operations are supported. The transfer consists of 512 bytes of data transferred in word
mode followed by 4 bytes of ECC transferred in byte mode. Because of the unique nature of the solid-state
CompactFlash Storage Card, the four bytes of ECC transferred by the host may be used by the CompactFlash
Storage Card. The CompactFlash Storage Card may discard these four bytes and write the sector with valid ECC
data. This command has the same protocol as the Write Sector(s) command. Use of this command is not
