This command enables and disables the attribute autosave function within the drive. This command allow the
drive to automatically save its updated attribute values to the attribute data sector at mode transition or cause
the autosave feature to be disabled. The state of the attribute autosave feature (either enabled or disabled)
will be preserved by the drive across power cycles.
A value of zero written by the host into the drive’s Sector Count register before issuing this command may
disable this function. Disabling this feature does not preclude the drive from saving attribute values to the
attribute data sector during other normal save operations.
A value of F1h written by the host into the drive’s Sector Count register before issuing this command will
cause this function to be enabled. Any other non-zero value written by the host into this register before issuing
this command will not change the state of the attribute autosave feature.
Upon receipt of the command from the host, the drive sets BSY, enables or disables the autosave function ,
clears BSY and asserts INTRQ.
