SLFLD25-xxxJ(I)
IDE FLASH DRIVE
Seek
(code: 7Xh)
This command is effectively a NOP command to the drive
although it does perform a range check.
Stand By Immediate
(code: E0h or 94h)
This command causes the drive to set BSY, enter the Standby
mode, clear BSY and return the interrupt immediately.
Set Features
(code: EFh)
This command is used by the host to establish or select
certain features.
Feature
Description
01H
Enable 8-bit data transfers
55H
Disable Read Look Ahead
66H
Disable Power on Reset (POR)
establishment of defaults at Soft Reset
81H
Disable 8-bit data transfers
BBH
4bytes of data apply on Read/Write
Long commands
CCH
Enable Power on Reset (POR)
establishment of default at Soft Reset
Translate Sector
(code: 87h)
This command allows the host a method of determining the
exact number of times a user sector has been erased and
programmed. This command is not supported.
Wear Level
(code: F5h)
This command is effectively a NOP command and only
implemented for backward compatibility. The Sector Count
Register will always be returned with an 00h indicating Wear
Level is not needed.
Write Buffer
(code: E8h)
This command enables the host to overwrite the contents of
the drive’s sector buffer with any data pattern desired.
Set Multiple Mode
(code: C6h)
This command enables the drive to perform Read and Write
Multiple operations and establishes the block count for these
commands.
Set Sleep Mode
(code: E6h or 99h)
This is the only command that allows the host to set the
ComapactFlash into Sleep mode. When the drive is set to
sleep mode, the ComapactFlash clears the BSY line and
issues an interrupt. The drive enters sleep mode and the only
method to make the drive active again (back to normal
operation) is by performing a hardware reset or a software
reset.
Stand By
(code: E2h or 96h)
This command sets the drive in Standby mode. If the Sector
Count Register is a value other than 0H, an Auto Power
Down is enabled and when the drive returns to the idle
mode, the timer starts a countdown. The time is set in the
Sector Count Register.
Write Long Sector
(code: 32h or 33h)
This command is provided for compatibility purposes and is
similar to the Write Sector(s) command except that it writes
516 bytes instead of 512 bytes.
Write Multiple
(code: C5h)
This command is similar to the Write Sectors command.
Interrupts are not presented on each sector, but on the
transfer of a block which contains the number of sectors
defined by Set Multiple command.
Write Multiple without Erase
(code: CDh)
This command is similar to the Write Multiple command
with the exception that an implied erase before the write
operation is not performed. Note that before using this
command, it is required to erase the repective sectors using
the Erase Sectors command.
