0132 
0133        A. WSS I/O requires a block of 8 I/O addresses ("ports"). Of these, the first
0134        4 are used to identify and configure the board. With the advent of PnP,
0135        these first 4 addresses have become obsolete, and software applications
0136        only use the last 4 addresses to control the codec chip. Therefore, the
0137        base address setting "skips past" the 4 unused addresses.
