Table 21 Vendor Specific PGA Default Values

VENDOR ID REGISTERS (INDEX 7CH TO 7EH)

This register is for specific vendor identification if so desired. The ID method is Microsoft’s Plug and

Play Vendor ID code. The first character of that ID is F7 to F0, the second character S7 to S0, and

the third T7 to T0. These three characters are ASCII encoded. The REV7 to REV0 field is for the

Vendor Revision number. In WM9704M the vendor ID is set to WML3 if MODE1 = 0, and WML4 if

MODE1 = 1.

Wolfson is a registered Microsoft Plug and Play vendor.
