- Bit 5:
The Device Write Fault (DF) bit. This bit indicates that a device fault
(write fault) condition has been detected.
If a write fault is detected during command execution, this bit is
latched and retained until the device accepts the next command or
reset.
- Bit 4:
Device Seek Complete (DSC) bit. This bit indicates that the device
heads are positioned over a track.
In the IDD, this bit is always set to 1 after the spin-up control is
completed.
- Bit 3:
Data Request (DRQ) bit. This bit indicates that the device is ready to
transfer data of word unit or byte unit between the host system and the
device.
- Bit 2:
Always 0.
- Bit 1:
Always 0.
- Bit 0:
Error (ERR) bit. This bit indicates that an error was detected while the
previous command was being executed. The Error register indicates
the additional information of the cause for the error.
(10) Command register (X’1F7’)
The Command register contains a command code being sent to the device. After
this register is written, the command execution starts immediately.
Table 5.3 lists the executable commands and their command codes. This table
also lists the necessary parameters for each command which are written to certain
registers before the Command register is written.
