158 	   4 are used to identify and configure the board. With the advent of PnP,
159 	   these first 4 addresses have become obsolete, and software applications
160 	   only use the last 4 addresses to control the codec chip. Therefore, the
161 	   base address setting "skips past" the 4 unused addresses.
