11.7.2 MMU Instruction Timing
11-60
The MMU instruction timing table lists the numbers of clock periods needed
for the MMU to perform the MMU instructions. The total number of clock
cycles is outside the parentheses. It includes the numbers of read, prefetch,
and write cycles, which are shown inside the parentheses as (r/pr/w).
NOTES:
***Number given is the maximum for a six-level table (FC lookup, a, b, c, and d levels with indirect level, all long
