Cause
Write/Read error of RAM
After the fixed time, the value of RAM is not
maintained.
The value at address A : from address B.
It was possible to read it.
Cause
It failed in reset of HDC.
It failed in Internal disk controller self-test.
It failed in the initialization of the hard disk
controller.
It failed in the lady check of the hard disk.
It failed in Recalibrate of the hard disk.
It failed in the seek of the maximum cylinder of the
hard disk.
It failed in the acquisition of the parameter of the
hard disk.
It is competition Area in the Write/Read test.
Cause
Illegal command
The address mark is not found.
The floppy disk is write-protected.
The sector is not found.
Floppy disks have been exchanged.
Overrunning of DMA
DMA exceeded the limitation of 64KB.
The track number is outside the range or media are
different.
Illegal CRC and ECC
The controller is abnormal.
The trouble was caused in seek.
Time-out
The effective operation failed.
Cause
Bit7-3 of the interrupt status is not 0.
Write/Read error of period of dividing frequency
register
In Internal Loopback Test, the flaming error or the
parity error or the overrunning error occurred.
In Internal Loopback Test, transmission data is not
corresponding to received data.
Either after the data transfer ends with Internal
