ATA Register Specifications

Data Register

This register is a 16 bit register which is used to transfer

data blocks between the card data buffer and the host.

Data may be transferred by either a series of word

accesses to the Data register or a series of byte accesses

to the Data register.

Error Register

This register contains additional information about the

source of an error which has occurred in processing of the

preceding command. This register should be checked by

the host when ERR bit in the Status register is set. The

Error register is a read only register.

function

This bit is set when a Bad Block is detected in requested ID

field. Host can not read/write on data area that is marked as

a Bad Block.

This bit is set when Uncorrectable error is occurred at

reading the card.

The requested sector ID is in error or cannot be found.

This bit is set if the command has been aborted because of

the card status condition. (Not ready, Write fault, etc.) or

when an invalid command has been issued.

This bit is set in case of a general error.

Feature Register

This register is written by the host to provide command

specific information to the drive regarding features of the

drive which the host wish to utilize. The Feature register is

a write only register.

Feature byte

Sector Count Register

This register is written by the host with the number of

sectors or blocks to be processed in the subsequent

command. After the command is complete, the host may

read this register to obtain the count of sectors left

unprocessed by the command.

ATA PC CARDS

Sector Number Register

This register is written by the host with the starting sector

number to be used in the subsequent Cylinder-Head-

Sector command. After the command is complete, the

host may read the final sector number from this register.

When logical block addressing is used, this register is

written by the host with bit7 to 0 of the starting logical

block number and contains bit7 to 0 of the final logical

block number after the command is complete.

Sector Number

Logical Block Number bits A07-A00(LBA Addressing)

Cylinder Low Register

This register is written by the host with the low-order byte

of the starting cylinder address to be used in the

subsequent Cylinder-Head-Sector command. After the

command is complete, the host may read the low-order

byte of the final cylinder number from this register. When

logical block addressing is used, this register is written by

the host with bits15 to 8 of the starting logical block

number and contains bits15 to 8 of the final logical block

number after the command complete.

Cylinder Low Byte

Logical Block Number bits A15-A08(LBA Addressing)

Cylinder High Register

This register is written by the host with the high-order byte

of the starting cylinder address to be used in the

subsequent Cylinder-Head-Sector command. After the

command is complete, the host may read the high-order

byte of the final cylinder number from this register. When

logical block addressing is used, this register is written by

the host with bits 23 to 16 of the starting logical block

number and contains bits23 to 16 of the final logical block

number after the command is complete.

Cylinder High Byte

Logical Block Number bits A23-A16(LBA Addressing)

Drive/Head Register

The Drive/Head register is used to specify the selected

drive of a pair of drives sharing a set of registers.

function

Undefined . “0” or “1”.

This bit is “0” for CHS addressing and “1” for Logical

Block addressing.

This bit is number of the drive which the host has

selected. When DRV is cleared, Drive0 is selected.

When DRV is set, Drive1 is selected. The card is

selected to be Drive0 or to be Drive1 using the “Copy”

field of the PC Card Socket Copy Register.
