A.2.4. JTAG Silicon ID (Offset 0x0C - 0x18)

This read-only register returns the JTAG Silicon ID. Intel programming software uses this JTAG ID to ensure that is is using the correct SRM Object File (*.sof).

These registers are only good for Port 0 ( PCIe* Gen4 x16). They are blocked for the other Ports.
