SIGNAL DESCRIPTIONS
		Table 8: Signal Descriptions
	Signal Name	Pin(s)	Type	Description
	A2-A0	36, 33,	I	Address Inputs. These signals are
		35		asserted by the host to access the task
				registers in the device.
	-CS0,-CS1	37, 38	I	In the true IDE mode, -CS0 is the chip
				select for the task file registers while -CS1
				is used to select the Alternate Status
				register and the Device Control register.
	-CSEL	28	I	Cable Select. This internally pulled-up
				signal is used to configure this device as a
				master or a slave when the jumper
				configuration is in CSEL mode.
				When this pin is:
				• Grounded by the host, this device is
				configured as a master.
				• Open, this device is configured as a
				slave.
	D15-D0	18, 16,	I/O	Data Inputs/Outputs. This is the 8-bit or
		14, 12,		16-bit bidirectional interface between the
		10, 8, 6,		host and device. The lower eight bits are
		4, 3, 5, 7,		used for 8-bit register transfers.
		9, 11, 13,
		15, 17
	-DMACK	29	I	DMA Acknowledge. This signal is used by
				the host in response to DMARQ to initiate
				DMA transfers. The DMARQ/-DMACK
				handshake is used to provide flow control
				during the transfer. When -DMACK is
				asserted, -CS0 and -CS1 are not asserted
				and transfers are 16-bits wide.
	DASP	39	I/O	Disk Active/Slave Present. This open
				drain output signal is asserted low any time
				the drive is active. In a master/slave

configuration, this signal is used by the slave to inform the master that a slave is present.
