 147
 148           A. WSS I/O requires a block of 8 I/O addresses ("ports"). Of these, the first
 149           4 are used to identify and configure the board. With the advent of PnP,
 150           these first 4 addresses have become obsolete, and software applications
 151           only use the last 4 addresses to control the codec chip. Therefore, the
 152           base address setting "skips past" the 4 unused addresses.
