Jumper Setting
==============
Master/Slave Setting
--------------------
When the drive is connected to the host bus, Master/Slave setting is
necessary to configure a drive as a master or a slave.
Master/Slave setting is established between drives on the interface
connector by using jumper 0-2 (pin# A,B,C).
The master drive is assigned to drive address 0, the slave drive is
assigned to drive address 1.

Description of the Interface Signals
------------------------------------
The interface is an ATA (IDE) interface. Reserved pins should be
left unconnected. The following table shows the signal definitions.
"I" of I/O type represents an input signal for the drive and "O"
represents an input signal from the drive.
+------------+-----+--------+---------------------------------------+
|Signal name | Pin |I/O type| Description |
|RESET- | 1 | I | This is a reset signal output from the|
| | | | host system and to be used for inter- |
| | | | face logical circuit. |
+------------+-----+--------+---------------------------------------+
|DD0-DD15 | 3-18| I/O | This is a 16 bit directional bus. The |
| | | | lower 8 bits are used for register |
| | | | access other than data register. |
+------------+-----+--------+---------------------------------------+
|DIOW- | 23 | I | The rising edge of this Write Strobe |
| | | | signal enables data from a register on|
| | | | the drive. |
+------------+-----+--------+---------------------------------------+
|DIOR- | 25 | I | Activating this Read Strobe signal |
| | | | enables data from a register on the |
| | | | drive to be clocked onto the host data|
| | | | bus. The rising edge of this signal |
| | | | latches data at the host. |
+------------+-----+--------+---------------------------------------+
|IORDY | 27 | O | This signal is used to temporarily |
| | | | stop the host register access (read or|
| | | | write) when the drive is not ready to |
| | | | respond to a data transfer request. |
+------------+-----+--------+---------------------------------------+
|CSEL | 28 | I | This signal is used to configure a |
| | | | drive as either Drive 0 or 1 when CSEL|
| | | | mode is selected. This signal is |
| | | | pulled up inside the drive. |
| | | | +-----+--------------+ |
| | | | |CSEL |Drive address | |
| | | | +-----+--------------+ |
| | | | |GND | 0 | |
| | | | +-----+--------------+ |
| | | | |OPEN | 1 | |
| | | | +-----+--------------+ |
+------------+-----+--------+---------------------------------------+
|INTRQ | 31 | O | This is an interruption signal for the|
| | | | host system. This signal is asserted |
| | | | by a selected drive when the nIEN bit |
| | | | in the Device Control Register is "0".|
| | | | In other cases, this signal should be |
| | | | a high impedance state. |
+------------+-----+--------+---------------------------------------+
|IOCS16- | 32 | O | This signal indicates to the host that|
| | | | the 16 bis data port has been |
| | | | addressed an a 16 bit word can be read|
| | | | or written to the drive. |
+------------+-----+--------+---------------------------------------+
|DA0-2 |33,35| I | This is a register address signal from|
| | 36 | | the host system. |
+------------+-----+--------+---------------------------------------+
|PDIAG- | 34 | I/O | This signal is asserted by Drive 1 to |
| | | | indicate to Drive 0 that it has |
| | | | completed diagnostics. This signal is |
| | | | pulled up inside the drive. |
+------------+-----+--------+---------------------------------------+
|CS1FX- | 37 | I | This drive chip selection signal is |
| | | | used to select the Command Block |
| | | | Registers from the host system. |
+------------+-----+--------+---------------------------------------+
|CS3FX- | 38 | I | This drive chip selection signal is |
| | | | used to select the Control Block |
| | | | Registers from the host system. |
+------------+-----+--------+---------------------------------------+
|DASP- | 39 | I/O | This signal indicates that a drive is |
| | | | active or that Drive 1 is present |
| | | | when power is turned on |
+------------+-----+--------+---------------------------------------+
|DMARQ | 21 | O | This signal, used for DMA data |
| | | | transfers between host and drive, |
| | | | shall be asserted by the drive when |
| | | | it is ready to transfer data. |
+------------+-----+--------+---------------------------------------+
|DMACK- | 29 | I | This signal shall be used by the host |
| | | | in reponse to DMARQ to either |
| | | | acknowledge that data has been |
| | | | accepted, or that data is available. |

Introduction
------------
The DK212/222A series disk drive embodies large capacity such as
1080MB, 810MB (19mm height) and 540MB (12.5mm height) in spite
of the small size (2.5 inch) by applying the latest high-density
record technology. It provides high performances such as 12ms of
average seeking time and up to 11MB of transmission rate (Pio mode3).
It also realizes high long-run reliability by reducing the number
of parts dramatically and controlling the quality severely. Compared
with 3.5 inch disk drives, the DK212/222 series disk drives improves
power consumption economy drastically. It supports the standard ATA-2
(IDE) interface.
Execute drive diagnostic [90h]
------------------------------
This command allows the drive to perform a self-diagnostics. When
DRV0 and DRV1 are connected in the daisy chain mode, this command
is executed for both of the drives.
When the drive receives this command, it sets BSY=1 and executes the
self-diagnostic operation. Then the drive registers the diagnostic
result in the Error register, clears BSY, and generates an interrupt.
