10.1.2.2 Error Register (Read Only) (See Table 10-1 for register addressing)
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:
Symbol
Function
BBK
This bit is set when a Bad Block is detected.
UNC
This bit is set when an Uncorrectable Error is encountered.
IDNF
The requested sector ID is in error or cannot be found.
ABRT
This bit is set if the command has been aborted because of an ATA flash disk controller
status condition: (Not Ready, Write Fault, etc.) or when an invalid command has been
issued.
AMNF
This bit is set in case of a general error.
10.1.2.3 Feature Register (Write Only) (See Table 10-1 for register addressing)
This register provides information regarding features of the ATA flash disk controller that the host can utilize.
10.1.2.4 Sector Count Register (See Table 10-1 for register addressing)
This register contains the numbers of sectors of data requested to be transferred on a Read or Write operation
between the host and the ATA flash disk controller. If the value in this register is zero, a count of 256 sectors is
specified. If the command was successful, this register is zero at command completion. If not successfully com-
pleted, the register contains the number of sectors that need to be transferred in order to complete the request.
10.1.2.5 Sector Number (LBA 7-0) Register (See Table 10-1 for register addressing)
This register contains the starting sector number or bits 7-0 of the Logical Block Address (LBA) for any ATA flash
disk controller data access for the subsequent command.
10.1.2.6 Cylinder Low (LBA 15-8) Register (See Table 10-1 for register addressing)
This register contains the low order 8 bits of the starting cylinder address or bits 15-8 of then Logical Block
Address.
10.1.2.7 Cylinder High (LBA 23-16) Register (See Table 10-1 for register addressing)
This register contains the high order bits of the starting cylinder address or bits 23-16 of the Logical Block Address.
