Normal Outputs
Upon successful completion of one or more outstanding commands, the device shall transmit a Set Device Bits FIS
with the Interrupt bit set to one and one or more bits set to one in the ACT field corresponding to the bit position for
each command TAG that has completed since the last status notification was transmitted. The ERR bit in the Status
register shall be cleared to zero and the value in the Error register shall be zero.
Error Outputs
If the device has received a command that has not yet been acknowledged by clearing the BSY bit to zero and an
error is encountered, the device shall transmit (see Table 115) with the ERR bit set to one and the BSY bit cleared to
zero in the Status field, the ATA error code in the Error field.
