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