15.4.1.20 BDT Page Register 2 (BDT_PAGE_02)
The Buffer Descriptor Table Page Register 2 contains an 8-bit value that is used to compute the address
where the current Buffer Descriptor Table (BDT) resides in system memory. See
Section 15.4.1.16, “BDT
Page Register 1 (BDT_PAGE_01) ” for more information on the format of the Buffer Descriptor Table.
Figure 15-27 shows the BDT Page Register 2.
15.4.1.21 BDT Page Register 3 (BDT_PAGE_03)
The Buffer Descriptor Table Page Register 3 contains an 8-bit value that is used to compute the address
where the current Buffer Descriptor Table (BDT) resides in system memory. See
Section 15.4.1.16, “BDT
Page Register 1 (BDT_PAGE_01) ” for more information on the format of the Buffer Descriptor Table.
Figure 15-28 shows the BDT Page Register 3.
