11.6 Address Decoding The host addresses the drive using programmed I/O. In this method, the required register address should be placed on the three host address lines, DA2 - DA0. An appropriate chip is selected and a read or write strode (-DIOR / -DIOW) shall be given to the chip. The following I/O map shows definitions of all the register addresses and functions for these I/O locations. The descriptions of each register are shown in the next paragraph. Table 11.
11.7 Register Description In the following register descriptions, unused write bit should be treated as “don't care”, and unused read bits should be read as zeros. 11.7.1 Data Register - CS0 DA2-DA0 : 0 Read / Write There are seven commands which execute data transfer from/to this register of the sector buffer for Read and Write operations. The sector table during Format command and the data associated with the Identify Device command shall also be transferred to this register. 11.7.1.
11.7.1.5 Security commands Password information is transferred during the execution of following four commands. 1) Disable password 2) Erase Unit 3) Set Password 4) Unlock Data in the register and on the media correspond to each other as follows: A15 - A8 D2 D4 : : D512 transfer 1 transfer 2 : : transfer 256 transfer 257 : : transfer 260 A7 - A0 D1 D3 : : D511 E1 E2 : E4 D1 DATA REGISTER D2 --- D512 E1 --- E4 DATA FLOW ON THE MEDIA 11.7.2 Error Register - CS0 DA2-DA0 : 1 Read ONLY 11.7.2.
11.7.2.2 Diagnostic Mode The drive enters diagnostic mode immediately after the power -on or after an Execute Diagnostics command. Error bit in Status Register shall not be set in these cases. The following table shows bit values for the diagnostic mode. Table 11.
11.7.5 Sector Number Register - CS0 DA2-DA0 : 3 Read / Write The target logical sector number (starting from 1) for Read, Write, and Verify commands is set in this register. After completion of a command, it shows the sector number of the last sector transferred to the host. The starting sector number is set in this register for multi-sector operations. But when error occurs during multi-sector transfer, it shows the number of the sector in which the error has been detected.
11.7.7.2 SMART commands This register should be set to C2h for SMART commands 11.7.8 Device/Head Register - CS0 DA2-DA0 : 6 Read / Write The value of this register is used to select the drive, Drive0 or Drive1, and head. On multiple sector read/write operation that requires to cross track boundaries, the head select bit will be updated to reflect the currently selected head number.
11.7.9 Status Register -CS0 DA2-DA0:7 Read only This register contains the command status. The contents of the register are updated at the completion of each command and whenever the error occurs. The host system reads this register in order to acknowledge the status and the result of each operation. When the BSY bit (bit 7) is set, no other bits in the register are valid.
11.7.10 Command Register - CS0 DA2-DA0 : 7 Write only The command register accepts commands for the drive to perform fixed disk operations. Commands are executed when the TASK FILE is loaded and the command register is written and only when: The status is not busy (BSY is inactive). and DRDY (drive ready) is active. Any code NOT defined in the following list causes an Aborted Command error. Interrupt request (INTRQ) is reset when a command is written.
Table 11.
Parameters are defined as follows. SC = SECTOR COUNT register. SN = SECTOR NUMBER register. CY = CYLINDER LOW and CYLINDER HIGH register.
11.7.11 Alternate Status Register - CS1 DA2-DA0 : 6 Read only This register contains the same information as the status register in the Task File. The only difference is that this register being read does not imply interrupt acknowledge or doesn’t reset a pending interrupt. See the description of status resister for definitions of the bit in this register. 11.7.12 Device Control Register - CS1 DA2-DA0 : 6 Write only This register contains the following three control bits.
11.8 Command Descriptions The drive interprets the commands written in the command register by the host system and executes them. This table shows the drive’s response to the valid commands written in command-register.

11.11 Adaptive Power Mode Control Adaptive Power Mode Control is a function to reduce power consumption without performance degradation. The drive supports the following Idle modes of 3 levels. The drive enters into idle mode adaptively in accordance with the command pattern. 11.11.1 Performance Idle The drive enters Performance Idle mode at the completion of a command from host. In this mode, electric circuit and servo is ready to process the next command without delay. 11.11.
11.12 Reset A RESET condition sets the drive ( or both drives in case of Drive0/Drive1 connection ) BSY, allowing the drive to perform the specified initialization required for normal operation. A RESET condition can be generated by both hardware and software. There are two hardware resets, one is by the Host (- RESET) and the other is by the drive power sense circuitry. These resets are set high when the system and the drive respectively acknowledge specified supply voltage ( See 6.1).
11.13 Drive0/Drive1 Configuration Drive address shall be set by the optional jumper of interface connector. The drive runs as Drive0 when the jumper is open or if jumper plug is set to position B-D when P28(CSEL) signal is low. The drive runs as Drive1 when the jumper plug is inserted into position C-D or if jumper plug is set to position B-D when P28 (CSEL) signal is high. In case of two- drive configuration, one shall be Drive0 and the other should be Drive1.
11.14 Cache Memory 11.14.1 Cache Operations (1) READ CACHE OPERATION Receiving a read command, the data in the buffer memory are sent to the host without access to the disk media as long as the object data reside in the buffer memory and the conditions for the drive’s read cache operation are fulfilled.
12. Protocol Commands can be grouped into different classes according to the protocols used for command execution. The command classes with their associated protocols are defined below. For all commands, the host first checks BSY bit and DRDY bit. If BSY＝1, the host should proceed no further unless and until the BSY＝0, and the DRDY＝1. Interrupts are cleared when host reads Status register, issues a reset, or writes to the Command register.
12.1 PIO data in commands Commands for this class are: • • • • • • • • • • IDENTIFY DEVICE READ BUFFER READ SECTOR(S) (with and without retry) READ SECTOR(S) EXT READ MULTIPLE READ MULTIPLE EXT SMART Read Attribute Values SMART Read Attribute Thresholds SMART Read Log Sector DEVICE CONFIGRATION IDENTIFY PIO data in protocol: a) The host writes any required command parameters to the Features, Sector Count, Sector Number, Cylinder High, Cylinder Low and Device/Head registers.
12.
The Write Multiple command transfers one block ( the number of sectors is defined by the Set Multiple command ) of data for each interrupt. The other commands transfer one sector of data for each interrupt. If the drive detects an invalid parameter in register setting, the drive clears the BSY bit and sets the ERR bit in the Status register and sets the ABRT bit in the Error register and asserts INTRQ to terminate the command execution.
Non-data protocol: a) The host writes any required command parameters to the Features, Sector Count, Sector Number, Cylinder High, Cylinder Low and Device/Head registers. b) The host writes the command code to the Command register. c) The drive sets the BSY bit . d) When the drive has finished processing a sector (or block) of data, it clears the BSY bit and asserts INTRQ. e) In response to the INTRQ, the host reads the Status register.

12.5 Ultra DMA Ultra DMA protocol is used with Read DMA, and Write DMA commands. Ultra DMA modes are set by Set features command. Since the setting after power-up ( Default setting ) is mode 2 of Multi Word DMA, Set Features command shall be issued to be used in Ultra DMA mode. An Ultra DMA data transfer is accomplished through a series of Ultra DMA data in or data out bursts.
3. Ultra DMA burst termination phase a) Either a sender or a recipient may terminate an Ultra DMA burst. b) Ultra DMA burst termination is not the same as command termination or completion. If an Ultra DMA burst termination occurs before the command is complete, the command shall be completed by initiation of a new Ultra DMA burst at some later time or aborted by the host issuing a hardware or software reset to the drive. c) An Ultra DMA shall be paused before a recipient requests a termination.
