9.3.2 ABORT bit
The ABORT bit is set to one if the device aborts the command. The ABORT bit is cleared to zero if the device does
not abort the command.
If the host requested an address outside of the range of user addressable addresses, then:
a) the ID NOT FOUND bit (see Section 9.3.4) is set to one and the ABORT bit is cleared to zero; or
b) the ID NOT FOUND bit is cleared to zero and the ABORT bit is set to one.
If a user addressable address was not found (see Section 9.3.4), the ABORT bit is cleared to zero.
If the INTERFACE CRC bit (see Section 9.3.6) is set to one, the ABORT bit is set to one.
9.3.3 COMMAND COMPLETION TIME OUT bit
The COMMAND COMPLETION TIME OUT bit shall be set to one if:
a) the STREAMING SUPPORTED bit is set to one (i.e., the Streaming feature set (see Section 10.12) is
supported); and
b) a command completion time out has occurred in response to a Streaming feature set command.
Otherwise, an ATA device shall clear the COMMAND COMPLETION TIME OUT bit to zero.
