|
|
|
Q. [Ports] Why is the base address of the WSS I/O ports off by 4? |
|
|
|
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. |
