Registers 60h-68h are the Extended CODEC Registers: These registers allow for the definition 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.
Extended Registers Page 00
Page 00 of the Extended CODEC Registers is reserved for vendor specific use. Driver writers should
not access these registers unless the Vendor ID register has been checked first to ensure that the
vendor of the AC '97 component has been identified and the usage of the vendor defined registers
understood.
Extended Registers Page 01
The usage of Page 01 of the Extended CODEC Registers is defined in Register 24h found in
Section7.1.17: page61.
Extended Registers Page 02, 03
Pages 02 and 03 of the Extended CODEC Registers are reserved for future use.
The AC’97 Specification Rev 2.3 uses a paging mechanism in order to increase the number of regis-
ters. The registers currently used in the paging are 60h to 6Eh. Additional information about the
Extended CODEC Registers, please refer to Section 7.3: page72.
One of two pages can be made active at any time, set in Register 24h. Register 24h is the Audio
Interrupt and Paging Register. Additional details about Register 24h is located in Section 7.1.17:
page61.
If page 00h is active, registers 60h to 6Eh are Vendor Specific.
If page 01h is active, registers 60h to 6Eh have the following functionality:
