5.5.2 Error Register (Address - 1F1[171];
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. The bits
are defined as follows:
D7 D6 D5 D4 D3 D2 D1 D0
BBK UNC 0 IDNF 0 ABRT 0 AMNF
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 SDP3B FlashDisk 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.
5.5.3 Feature Register (Address - 1F1[171];
Offset 1, 0Dh Write Only)
This register provides information regarding
features of the SDP3B FlashDisk that the host
can utilize. This register is also accessed on data
bits D15-D8 during a write operation to Offset 0
with -CE2 low and -CE1 high.
5.5.4 Sector Count Register
(Address - 1F2[172]; Offset 2)
This register contains the number of sectors of data
requested to be transferred on a read or write
operation between the host and the SDP3B
FlashDisk. 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 completed, the
register contains the number of sectors that need to
be transferred in order to complete the request.
5.5.5 Sector Number (LBA 7-0) Register
(Address - 1F3[173]; Offset 3)
This register contains the starting sector number or
bits 7-0 of the Logical Block Address (LBA) for
any SDP3B FlashDisk data access for the
subsequent command.
5.5.6 Cylinder Low (LBA 15-8) Register
(Address - 1F4[174]; Offset 4)
This register contains the low order 8 bits of the
starting cylinder address or bits 15-8 of the
Logical Block Address.
5.5.7 Cylinder High (LBA 23-16) Register
(Address - 1F5[175]; Offset 5)
This register contains the high order bits of the
starting cylinder address or bits 23-16 of the
Logical Block Address.
