NOTES:
1.
The Family corresponds to bits [11:8] of the EDX register after RESET, bits [11:8] of
the EAX register after the CPUID instruction is executed with a 1 in the EAX register,
and the generation field of the Device ID registers accessible through Boundary Scan.
2.
The Model corresponds to bits [7:4] of the EDX register after RESET, bits [7:4] of the
EAX register after the CPUID instruction is executed with a 1 in the EAX register, and
the model field of the Device ID registers accessible through Boundary Scan.
3.
The Brand ID corresponds to bits [7:0] of the EBX register after the CPUID instruction is
executed with a 1 in the EAX register.
