157 Q. [Ports] Why is the base address of the WSS I/O ports off by 4?
158
159 A. WSS I/O requires a block of 8 I/O addresses ("ports"). Of these, the first
160 4 are used to identify and configure the board. With the advent of PnP,
161 these first 4 addresses have become obsolete, and software applications
162 only use the last 4 addresses to control the codec chip. Therefore, the
163 base address setting "skips past" the 4 unused addresses.
