The Data Register is a 16 bit register, and it is used to transfer data blocks between the CompactFlash
Storage Card data buffer and the Host. This register overlaps the Error Register.
Error Register (Address - 1F1h[171h]; Offset 1, 0Dh Read Only)
This register contains additional information about the source of an error when an error is indicated in bit 0
of the Status register.
This register is also accessed in PC Card Modes on data bits D15-D8 during a read operation to offset 0
with -CE2 low and -CE1 high.
Bit 7 (BBK/ICRC): this bit is set when a Bad Block is detected. This bit is also set when an interface CRC
error is detected in True IDE Ultra DMA modes of operation.
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.
