CF-ATA command description
SMCxxxBF
10.23
Wear Level command (F5h)
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.
Table 77 defines the Wear Level command byte sequence.
10.24
Write buffer command (E8h)
The Write Buffer command enables the host to overwrite contents of the 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.
Table 78 defines the Write Buffer command byte sequence.
