Read Long Sector
The Read Long command performs similarly to the Read Sector(s) command except that it returns 516 bytes of
data instead of 512 bytes. During a Read Long command, the CompactFlash Storage Card does not check the
ECC bytes to determine if there has been a data error. Only single sector read long operations are supported. The
transfer consists of 512 bytes of data transferred in word mode followed by 4 bytes of ECC data transferred in byte
mode. This command has the same protocol as the Read Sector(s) command. Use of this command is not
recommended.

Read Sector(s)
This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector 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 CompactFlash Storage
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.
