SVID—Subsystem Vendor Identification Register
(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
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 Identification Register
(Modem—D31:F6)
