The cache is enabled or disabled using the CE bit of the cache control register (CCR). CCR also
has a CF bit (which invalidates all cache entries), and a WT and CB bits (which select either write-
through mode or write-back mode). Programs that change the contents of the CCR register should
be placed in address space that is not cached. When updating the contents of the CCR register,
always set bits 4 to 0. Figure 5.2 shows the configuration of the CCR register.
