Wear Level

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

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

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
