Error Register
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 not valid 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 happened.
3) Feature Register(Address – 1F1h[171h];Offset 1,0Dh Writer Only)
This register provides information regarding features of the CompactFlash Storage Card that the host can utilize.
