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.

(1) Master (or single)

  +43-------------------1---C-A-+
  | o o ----------- o o o   o o | If all of pin# A, B, C are open,
  | o o ----------- o o o   o o | the drive is a master (or single).

(2) Slave

  +43-------------------1---C-A-+
  | o o ----------- o o o   o X | If Jumper Position A-B is used,
  | o o ----------- o o o   o X | the drive is slave.

  | o o ----------- o o o   xxx | If Jumper Position A-C is used,
  | o o ----------- o o o   o o | Master/Slave setting is determinated
  +44-------------------2---D-B-+ by the condition of CSEL signal
                                  (pin# 28).

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.           |

 |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 |

 +------------+-----+--------+---------------------------------------+
 |CS1FX-      | 37  |   I    | This drive chip selection signal is   |
 |            |     |        | used to select the Command Block      |
 |            |     |        | Registers from the host system.       |
 +------------+-----+--------+---------------------------------------+

Features

HITACHI DK212A/222A DISK DRIVE SPECIFICATION REV. 7 K6600782 10/95

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.

 Diagnostic Codes
 +------+---------------------+
 | Code |  Contents           |
 +------+---------------------+
 | 01   |  NO ERROR           |
 +------+---------------------+
 | 02   |  CONTROLLER ERROR   |
 +------+---------------------+
 | 03   |  SECTOR BUFFER ERROR|
 +------+---------------------+
 | 04   |  ECC CIRCUITRY ERROR|
 +------+---------------------+
 | 05   |  CPU ERROR          |
 +------+---------------------+
 | 8X   |  DRV1 ERROR         |
