XSHDR0 (sector header 0: output)

ATAPI: Strobe negative logic input signal for reading data from the host.

DMA: Strobe negative logic input signal for reading data to the host.

AV: Negative logic output signal indicating the lead byte of the sector.

(5)XHWR (HOST write: input)/XHWR (HOST write: output)/DCK

(data clock: output)

ATAPI: Strobe negative logic input signal for writing data from the host.

DMA: Strobe negative logic output signal for writing data to the host.

AV: Clock output for data transfer.

(6)XHAC (HOST DMA acknowledge: input)/HDRQ (HOST DMA

request: input)/REQUEST (request:input) This pin is pulled up by a resistor.

ATAPI: DMA acknowledge negative logic input signal from the host.

DMA: DMA request input signal from the host.

AV: Data transfer request input signal.

(7)DASP (drive active/slave present: input/output)/pull up/pull up

ATAPI: Negative logic signal indicating that a slave drive is present or a drive is active; open drain signal.

DMA/AV: This pin is not used, and should be pulled up by a resistor.

(8)HDB[F:0] (HOST data bus: input/output)/HDB[F:0] (HOST data

bus: input/output)/7 “0”, XVFLAG,

DATA[7:0] (“0”, video error flag, data: output)

ATAPI/DMA: 16-bit host data bus.

AV: Low level is output from the upper 7 bits. The 8th bit from the upper side is an error flag output signal corresponding to the lower 8 bits. The lower 8 bits are video data output signals.

(9)HDRQ (HOST DMA request: output)/XHAC (HOST DMA

acknowledge: output)/XACK (acknowledge:output)

ATAPI: DMA data request positive logic output signal to the host; tri-state signal.

DMA: DMA acknowledge negative logic output signal to the host.

AV: Data transfer acknowledge negative logic output signal.

(10)HINT (HOST interrupt: output)/pull up/pull up

ATAPI: Interrupt request positive logic output signal to the host; tri-state signal.

DMA/AV: This pin is not used, and should be pulled up by a resistor.

(11)XS16 (16-bit data transfer: output)/pull up/pull up

ATAPI: Negative logic signal indicating that a 16-bit data port has been selected; open drain

signal. This is connected with the IOCS16 pin of the ATAPI interface.

DMA/AV: This pin is not used, and should be pulled up by a resistor.

(12)REDY (I/O channel ready: output)/pull up/pull up

ATAPI: Positive logic signal which is negated when a drive is

not ready to respond to a data transfer request; open drain signal. This is connected with the IORDY pin of the ATAPI interface.

DMA/AV: This pin is not used, and should be pulled up by a resistor.

(13)XPDI (passed diagnostics: input/output)/pull up/pull up

ATAPI: Negative logic signal indicating that diagnostics of the slave drive have been completed; open drain signal. This is connected with the PDIAG pin of the ATAPI interface. DMA/AV: This pin is not used, and should be pulled up by a resistor.

(14)XHRS (HOST reset: input)/nc/nc

ATAPI: Reset negative logic signal from the host; pulled up by a resistor.

DMA/AV: This pin is not used
