2.1.8 Read DMA (C8h)
Read data from sectors during Ultra DMA and Multiword DMA transfer. Use the SET FEATURES command to
specify the mode value. A sector count of zero requests 256 sectors.
2.1.9 Read Multiple (C4h)
This command performs similarity to the Read Sectors command. Interrupts are not generated on each sector,
but on the transfer of a block which contains the number of sectors defined by a Set Multiple command.
2.1.10 Read Sector(s) (20h)
This command reads 1 to 256 sectors as specified in the Sector Count register from sectors which is set by
Sector number register. A sector count of zero requests 256 sectors. The transfer beings specified in the
Sector Number register.
2.1.11 Read Verify Sector(s) (40h)
This command verifies one or more sectors on the drive by transferring data from the flash media to the data
buffer in the drive and verifying that the ECC is correct. This command is identical to the Read Sectors
command, except the DRQ is never set and no data is transferred to the host.
2.1.12 Recalibrate (10h)
The current drive performs no processing if it receives this command. It is supported for backward
compatibility with previous devices.
2.1.13 Security Disable Password (F6h)
Disables any previously set user password and cancels the lock. The host transfers 512 bytes of data, as
shown in the following table, to the drive. The transferred data contains a user or master password, which the
drive compares with the saved password. If they match, the drive cancels the lock. The master password is
still saved. It is re-enabled by issuing the SECURITY SET PASSWORD command to reset a user password.
2.1.14 Security Erase Prepare (F3h)
This command shall be issued immediately before the Security Erase Unit command to enable erasing and
unlocking. This command prevents accidental loss of data on the drive.
2.1.15 Security Erase Unit (F4h)
The host uses this command to transfer 512 bytes of data, as shown in the following table, to the drive. The
transferred data contains a user or master password, which the drive compares with the saved password. If
they match, the drive deletes user data, disables the user password, and cancels the locks. The master
password is still saved. It is re-enabled by issuing the SECURITY SET PASSWORD command to reset a user
password.
