6.0 ATA Command Description

This section defines the software requirements and
the format of the commands the host sends to the
FlashDrives.  Commands  are  issued  to  the
FlashDrive 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 6-1) of command acceptance, all
dependent on the host not issuing commands unless
the FlashDrive is not busy . (The BUSY bit in the
status and alternate status registers is 0.)

•

Upon receipt of a Class 1 command, the
FlashDrive sets the BUSY bit within 400
nsec.

•

Upon  receipt  of  a  Class  2  command,  the
FlashDrive  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
FlashDrive  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.

6.1

ATA Command Set

Table 6-1 summarizes the ATA command set with
the paragraphs that follow describing the
individual commands and the task file for each.
