Description
Re-Fetch Inhibit after LDTLB Execution
This bit controls whether re-fetch is performed for the
next instruction after the LDTLB instruction has been
executed.
0: Re-fetch is performed
1: Re-fetch is not performed
Re-Fetch Inhibit after Writing Memory-Mapped TLB
This bit controls whether re-fetch is performed for the
next instruction after writing memory-mapped
ITLB/UTLB while the AT bit in MMUCR is set to 1.
0: Re-fetch is performed
1: Re-fetch is not performed
Re-Fetch Inhibit after Writing Memory-Mapped IC
