SVID—Subsystem Vendor ID (Modem—D31:F6)
Address Offset:
Default Value:
Lockable:
The SVID register, in combination with the Subsystem ID register, enable the operating
environment to distinguish one audio subsystem from the other(s). This register is implemented as
a write-once register. Once a value is written to it, the value can be read back. Any subsequent
writes will have no effect. This register is not affected by the D3
SID—Subsystem ID (Modem—D31:F6)
Address Offset:
Default Value:
Lockable:
The SID register, in combination with the Subsystem Vendor ID register make it possible for the
operating environment to distinguish one audio subsystem from another. This register is
implemented as write-once register. Once a value is written to it, the value can be read back. Any
subsequent writes will have no effect.
This register is not affected by the D3
CAP_PTR—Capabilities Pointer (Modem—D31:F6)
