TLB entries consist of two parts:
The valid parameter specifies whether an entry is valid or not. The preserved parameter determines the behavior of an entry in the event of a TLB flush. If an entry is set as preserved, it is not deleted when a TLB is flushed, that is, when MMU_GFLUSH[0] GLOBALFLUSH is set to 1. Preserved entries must be deleted manually. Section 22.3.1.2.2, First-Level Translation Table describes the procedure to delete TLB entries.
Figure 22-17 shows the TLB entry structure.
