Non-Data Commands - Toshiba MK6017MAP Product Specification

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.
If an unrecoverable error occurs, the drive sets the DRQ bit and clears the BSY bit and sets the ERR bit and
stores the error status in Error register and report the address information of the sector with error to Sector
Number, Cylinder High, Cylinder Low and Device/Head registers and asserts INTRQ.

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.
f) The drive negates INTRQ in response to the Status register being read
