ASM is Oracle managed disks.  Backups are backups.  The two really aren't related.

What are you thinking when asking to use ASM for backups?

If your database is using ASM, then the controlfile and redo logs already are in ASM storage.

Here is an example of an ASM directory structure:
+DATA
  ORCLPRO1
	ARCHIVELOG
	BACKUPSET
	CONTROLFILE
	DATAFILE
	DATAGUARDCONFIG
	ONLINELOG
	PARAMETERFILE
	TEMPFILE
  dr1orclpro1.dat
  dr2orclpro1.dat
  spfileorclpro1.ora

>>my question is ...

Sorry but I still do not understand.

ASM is Oracle's disk management product.  Backups write to disk or tape.  I don't think you can use ASM disks as a backup destination if that is what you are asking.  Once you allocate space to ASM, it is are under the control of ASM and cannot use the space for anything else.

You can set your backup disk to ASM disk by creating a new new disk group for backup

As the article posted states, rman can use the FLASH_RECOVERY_AREA in ASM, for backups.
