4.3 Interface Registers

4.3.1 I/O registers

This section provides the I/O register functions and mapping. Definitions of each register vary depending on which ATA or ATAPI commands are used.

Table 4.3 I/O port functions and mapping

	Address signal				Function

CS0-	CS1-	DA2	DA1	DA0	READ (DIOR-)		WRITE (DIOW-)

N	N	x	x	x	High impedance state		Ineffective

					Control block register

N	A	0	x	x	High impedance state		Ineffective

N	A	1	0	x	High impedance state		Ineffective

N	A	1	1	0	Alternate Status		Device Control

N	A	1	1	1	Drive Address		Ineffective

					Command block register

A	N	0	0	0		Data

A	N	0	0	1	Error		ATA Features (ATA)
							ATAPI Features (ATAPI)

A	N	0	1	0	Sector Count (ATA)

					ATAPI Interrupt Reason		Ineffective
					(ATAPI)

A	N	0	1	1	Sector Number

A	N	1	0	0	Cylinder Low (ATA)
					ATAPI Byte Count (bits 0-7) (ATAPI)

A	N	1	0	1	Cylinder High (ATA)
					ATAPI Byte Count (bits8-15) (ATAPI)

A	N	1	1	0	Device/Head (ATA)
					ATAPI Block Device Select (ATAPI)

A	N	1	1	1	ATAPI Status		ATA Command

A	A	x	x	x	Ineffective		Ineffective

The letter A indicates that the bit is asserted, N indicates that the bit is negated, and X indicates that the bit is ignored.
