Host Interface

The Verify mode setting in the mode parameter (Verify Control Page) can be set to omit verify processing. Omitting verify processing shortens processing time by about 25%.

The WRITE (10) command receives the specified number of blocks of data and begins writes it beginning at the specified logical block address. Logical Block Address specifies the logical block address at which the command should start writing data. Transfer Length specifies the number of blocks of data to be transferred and written. If Transfer Length is 0, the command transfers no data. It simply ends normally without writing any data.

The WRITE AND VERIFY command receives the specified number of blocks of data and writes it beginning at the specified logical block address. Logical Block Address specifies the logical block address at which the command should start writing data. Transfer Length specifies the number of blocks of data to be transferred and written.

The ByteChk bit controls data compare processing. However, since the ODD does not support ByteChk, it must be set to 0. If 1 is specified, the command ends with Check Condition. If Transfer Length is 0, the command transfers no data. It simply ends normally without writing any data.
