5. ATA Command Description
This section defines the software requirements and the format of the commands the host sends to the CompactFlash
Memory Cards. Commands are issued to the CompactFlash Card by loading the required registers in the command
block with the supplied parameters, and then writing the command code to the Command Register. The manner in
which a command is accepted varies. There are three classes (see Table 5-1) of command acceptance, all dependent
on the host not issuing commands unless the CompactFlash Card is not busy. (The BUSY bit in the status and
alternate status registers is 0.)
5.1. ATA Command Set
Table 5-1 summarizes the ATA command set with the paragraphs that follow describing the individual commands
and the task file for each.

Upon receipt of a Class 1 command, the CompactFlash Card sets the BUSY bit within 400 nsec.
Upon receipt of a Class 2 command, the CompactFlash Memory Card sets the BUSY bit within 400
nsec, sets up the sector buffer for a write operation, sets DRQ within 700 µsec, and clears the BUSY
bit within 400 nsec of setting DRQ.
Upon receipt of a Class 3 command, the CompactFlash Memory Card sets the BUSY bit within 400
nsec, sets up the sector buffer for a write operation, sets DRQ within 20 msec (assuming no re-
assignments), and clears the BUSY bit within 400 nsec of setting DRQ.
