DESCRIPTION
Relative cylinder offset from present cylinder as used by the Relative
Seek command.
The number of sectors per track to be initialized by the Format
command. The number of sectors per track to be verified during a
Verify command when EC is set.
When set to 1, sectors containing a deleted data address mark will
automatically be skipped during the execution of Read Data. If Read
Deleted is executed, only sectors with a deleted address mark will be
accessed. When set to “0”, the sector is read or written the same as
the read and write commands.
The time interval between step pulses issued by the FDC.
Programmable from 0.5 to 8 milliseconds in increments of 0.5 ms at
the 1 Mbit data rate. Refer to the SPECIFY command for actual
delays.
Registers within the FDC which store status information after a
command has been executed. This status information is available to
the host during the result phase after command execution.
Alters timing of WE to allow for pre-erase loads in perpendicular
drives.
