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.
