Extended CODEC Registers Page Structure Definition
Registers 60h-68h are the Extended CODEC Registers: These registers allow for the defi-
nition of further capabilities. These bits provide a paged address space for extended
CODEC information. The Page Selector bits in the Audio Interrupt and Paging register
(Register 24h bits 3:0) control the page of information viewed through this page window.
