Note
Because the same register, CP15 c1, controls the enabling of the ICache, DCache, and
the MMU, all three can be enabled using a single MCR instruction.
3.6.2 Disabling the MMU
To disable the MMU, clear bit 0 in CP15 c1.
Note
If the MMU is enabled, then disabled, and subsequently re-enabled, the contents of the
TLB are preserved. If these are now invalid, then the TLB must be invalidated before
re-enabling the MMU. See TLB Operations Register c8 on page 2-24.
