Datasheet
5.1.11 Read Verify Sector(s) – 40h, 41h
The Read Verify Sectors command verifies one or more sectors on DiskOnChip IDE Pro by
transferring data from the flash media to the data buffer in the controller and verifying that the ECC
is correct. This command is performed identically to the Read Sector(s) command, except that DRQ
is not asserted, and no data is transferred to the host.
When the command is accepted, DiskOnChip IDE Pro sets BSY. When the requested sectors have
been verified, DiskOnChip IDE Pro clears BSY and generates an interrupt. Upon command
completion, the Command Block registers contain the cylinder, head, and sector number of the last
sector verified. If an error occurs, the command terminates at the sector where the error occurs. The
Command Block registers contain the cylinder, head and sector number of the sector where the
error occurred. The Sector Count register contains the number of sectors not yet verified.
