11.2 ATA Flash Disk Controller Command Description
This section defines the software requirements and the format of the commands the host sends to the ATA Flash Disk
Controller. Commands are issued to the ATA Flash Disk Controller 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 11-2) of command acceptance, all dependent on the
host not issuing commands unless the ATA Flash Disk Controller is not busy (BSY=0).

Table 11-2 summarizes the ATA Flash Disk Controller command set with the paragraphs that follow describing the
