The two Vendor ID registers provide a means to determine the manufacturer of the AC ’97 audio codec. The first three
bytes of the Vendor ID registers contain the ASCII code for the first three letters of Crystal (CRY). The final byte of the
Vendor ID registers is divided into a Device ID field and a Revision field. Table 22 lists the currently defined Device ID’s.

First Character of Vendor ID. With a value of F[7:0] = 43h, these bits define the ASCII ‘C’ char-
Second Character of Vendor ID. With a value of S[7:0] = 52h, these bits define the ASCII ‘R’ char-
4352h. This register contains read-only data.
Third Character of Vendor ID. With a value of T[7:0] = 59h, these bits define the ASCII ‘Y’ char-
Device ID. With a value of DID[2:0] = 101, these bits specify the audio codec is a CS4205.
Revision. With a value of REV[2:0] = 001, these bits specify the audio codec revision is ‘A’.
