CHAPTER 5
5.1
This section defines the software requirements and the format of commands the host sends to
CompactFlash Memory cards. Commands are issued to the 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 card is not busy. (The BUSY bit in the status and alternate status registers
is 0.)

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.
Table 5-1
Class
Upon receipt of a Class 1 command, the card sets the BUSY bit within 400 nsec.
Upon receipt of a Class 2 command, the 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 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.
