TLBS – Search TLB For Entry
Architecture revision:
Architecture revision1 and higher.
Description
Search the addressed TLB for an entry matching TLB Entry High and Low (TLBEHI/TLBELO)
registers. Return a pointer to the entry in MMUCR[IRP] or MMUCR[DRP] if a match found, oth-
erwise set the Not Found bit in the MMU control register, MMUCR[N].
