Feedback by Ved Shanbhogue:

Would it be better if the example was representative of the only N values (N=16) supported by the extension?

Also the current example in the spec is wrong. The hex doesn't match the binary:

0xAAFFFFFF12345678
NVBITS[1010101] VBITS[11111111111111111111111110001...000]

Bit 56 is set, so this is 0xABFFFFFF12345678.
