[Command Set Descriptions]
1. CHECK POWER MODE (code: E5h);
This command checks the power mode.
2. EXECUTE DEVICE DIAGNOSTIC (code: 90h);
This command performs the internal diagnostic tests implemented by the module.
3. IDENTIFY DEVICE (code: ECh);
The IDENTIFY DEVICE command enables the host to receive parameter information from the module.
4. IDLE (code: 97h or E3h);
This command allows the host to place the module in the Idle mode and also set the Standby timer.
H_INTRQ_P may be asserted even through the module may not have fully transitioned to Idle mode. If
the Sector Count register is non-”0”, then the Standby timer shall be enabled. The value in the Sector
Count register shall be used to determine the time programmed into the Standby timer. If the Sector
Count register is “0” then the Standby timer is disabled.
5. IDLE IMMEDIATE (code: 95h or E1h);
This command causes the module to set BSY, enter the Idle (Read) mode, clear BSY and generate an
interrupt.
6. INITIALIZE DEVICE PARAMETERS (code: 91h);
This command enables the host to set the number of sectors per track and the number of heads per
cylinder.
7. NOP (code: 00h);
If this command is issued, the module respond with command aborted.
8. READ BUFFER (code: E4h);
This command enables the host to read the current contents of the module's sector buffer.
9. READ DMA (code: C8h,C9h);
This command reads from “1” to “256” sectors as specified in the Sector Count register using the DMA
data transfer protocol. A sector count of “0” requests “256” sectors transfer. The transfer begins at the
sector specified in the Sector Number register.
10. READ MULTIPLE (code: C4h);
This command performs similarly to the READ SECTORS command. Interrupts are not generated on
each sector, but on the transfer of a block which contains the number of sectors defined by a Set Multiple
commands.
11. READ NATIVE MAX ADDRESS (code: F8h);
This command returns the native maximum address.
12. READ LONG SECTOR (code: 22h, 23h);
This command is provided for compatibility purposes and nearly performs “1” sector READ SECTOR
command except that it transfers the data and 4 bytes appended to the sector. These appended 4 bytes
are all 0 data.
13. READ SECTOR(S) (code: 20h or 21h);
This command reads from “1” to “256” sectors as specified in the Sector Count register. A sector count of
“0” requests “256” sectors transfer. The transfer begins at the sector specified in the Sector Number
register.
14. READ VERIFY SECTOR(S) (code: 40h or 41h);
