Vendor ID1 Register (Index 7Ch)
F[7:0]
First Character of Vendor ID. With a value of F[7:0] = 43h, these bits define the ASCII ‘C’
character.
S[7:0]
Second Character of Vendor ID. With a value of S[7:0] = 52h, these bits define the ASCII ‘R’
character.
Default
4352h. This register contains read-only data.
4.22
Vendor ID2 Register (Index 7Eh)
T[7:0]
Third Character of Vendor ID. With a value of T[7:0] = 59h, these bits define the ASCII ‘Y’
character.
DID[2:0]
Device ID. With a value of DID[2:0] = 011, these bits specify the audio codec is a CS4299.
REV[2:0]
Revision. With a value of REV[2:0] = 001, these bits specify the audio codec revision is ‘A’.
Default
593xh. This register contains read-only data.
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 9 lists the currently defined
Device ID’s. Table 10 lists the current revisions of the CS4299.
