ATA Register Set Definitions:
Error Register
This register contains additional information about the source of an error when an error is indicated in bit 0
of the Status register. The bits are defined as follows:
This register is also accessed on data bits D15-D8 during a write operation to offset 0 with -CE2 low and
-CE1 high.
Bit 7 (BBK): This bit is set when a Bad Block is detected.
Bit 6 (UNC): This bit is set when an Uncorrectable Error is encountered.
Bit 5: This bit is 0.
Bit 4 (IDNF): The requested sector ID is in error or cannot be found.
Bit 3: This bit is 0.
Bit 2 (Abort): This bit is set if the command has been aborted because of a CompactFlash Storage Card
status condition: (Not Ready, Write Fault, etc.) or when an invalid command has been issued.
Bit 1 This bit is 0.
Bit 0 (AMNF) This bit is set in case of a general error.
Device/Head Register
The Drive/Head register is used to select the drive and head. It is also used to select LBA addressing
instead of cylinder/head/sector addressing. The bits are defined as follows:
Bit 7: This bit is set to 1.
Bit 6: LBA is a flag to select either Cylinder/Head/Sector (CHS) or Logical Block Address Mode (LBA).
When LBA=0, Cylinder/Head/Sector mode is selected. When LBA=1, Logical Block Address is
selected. In Logical Block Mode, the Logical Block Address is interpreted as follows:
LBA7-LBA0: Sector Number Register D7-D0.
LBA15-LBA8: Cylinder Low Register D7-D0.
LBA23-LBA16: Cylinder High Register D7-D0.
LBA27-LBA24: Drive/Head Register bits HS3-HS0.
