6.1.14 Read Sectors – 20H or 21H
This command reads from 1 to 256 sectors as specified in the Sector Count register. A sectors count of 0
requests 256 sectors. The transfer begins at the sector specified in the Sector Number register. When this
command is issued and after each sector of data (except the last one) has been read by the host, the
compact flash card sets BSY, puts the sector of data in the buffer, sets DRQ, clears BSY, and generates
an interrupt. The host then reads the 512 bytes of data from the buffer.
At command completion, the Command Block registers contain the cylinder, head and sector number of
the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The
Command Block registers contain the cylinder, head, and sector number of the sector where the error
occurred. The flawed data is pending in the sector buffer.
6.1.15 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 compact flash card sets BSY.
When the requested sectors have been verified, the compact flash 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.
