This register contains the numbers of sectors of data requested to be transferred on a read or
write operation between the host and the CompactFlash Storage Card. 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.
BIT DESCRIPTION-
5) Sector Number (LBA 7-0) Register(Address–1F3h[173h];Offset 3)
This register contains the starting sector number or bits 7-0 of the Logical Block Address (LBA)
for any CompactFlash Storage Card data access for the subsequent command.
6) Cylinder Low (LBA 15-8 )Register (Address–1F4h[174h];Offset 4)
This register contains the low order 8 bits of the starting cylinder address or bits 15-8 of the
Logical Block Address.
DIT DESCRIPTION-
7) Cylinder High(LBA 23–16)Register(Address–1F5h[175h]; Offset 6)
This register contains the high order bits of the starting cylinder address or bits 23-16 of the
Logical Block Address.
BIT DESCRIPTION-
8) Status/Alternate Status Register(Address 1F7h[177h]/3F6h[376h];Offset 7/ Eh)
These registers return the CompactFlash Storage Card status when read by the host. Reading
the Status register does clear a pending interrupt, while reading the Alternate Status register does not. The status
bits are described as follows:
