7.3.2. Level 1 fetch

Bits [31:14] of the Translation Table Base register are concatenated with bits [31:20] of the virtual address to produce a 30-bit address as illustrated in Figure 7.2. This address selects a 4‑byte translation table entry which is a First Level Descriptor for either a Section or a Page (bit 1 of the returned descriptor specifies whether it is for a Section or Page). This is shown in Figure 7.2.
