Page Selector
0h = Vendor Specific
1h = Page ID 01 (See Section 8.4 for additional information on the
Paging Registers)
Fh = Reserved Pages
This register is used to select a descriptor of 16 word pages
between registers 60h to 6Fh. Value 0h is used to select vendor
specific space to maintain compatibility with AC’97 2.2 vendor
specific registers.
System software determines implemented pages by writing the
page number and reading the value back. All implemented pages
must be consecutive. (i.e., page 2h cannot be implemented without
page 1h).
These registers are not reset on RESET#.
