3.2.1.13 Read Verify Sector(s) - 40H or 41H

This command is identical to the Read Sectors command, except that DRQ is never set and no data is

transferred to the host. When the command is accepted, the CompactFlash card sets BSY.

When the requested sectors have been verified, the CompactFlash card 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 verify 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.

3.2.1.14 Recalibrate - 1XH

This command is effectively a NOP command to the CompactFlash card and is provided for

compatibility purposes.

3.2.1.15 Request Sense - 03H

This command requests extended error information for the previous command. Table 3-9 defines the

valid extended error codes for the CompactFlash card Series product. The extended error code is

returned to the host in the Error Register.
