BDTPTRH<23:16>: Buffer Descriptor Table Base Address bits
This 8-bit value provides address bits 23 through 16 of the Buffer Descriptor Table base address, which
defines the starting location of the Buffer Descriptor Table in system memory.
The 32-bit Buffer Descriptor Table base address is 512-byte aligned.
