Bits 7–0: TLBVALID: TLB Valid Indicator

Displays the valid bits for the eight TLB slots in a single byte.

Note: This register may be used to clear multiple valid bits simultaneously. For all writes, bits with a

value of ‘0’ will cause the associated valid bit to be cleared, and bits with a value of ‘1’ will be

ignored. For example, writing 0xFE to this register will clear the valid bit for TLB0.
