## How can I interact with MMU/TLB?
By default Unicorn will emulate the MMU depending on the emulated architecture.
So you can use the features and interfaces of this MMU.
You or the emulated code can write to the memory and corresponding register to use the MMU.
There is also use the `UC_TLB_VIRTUAL` mode.
This mode defaults to a simple paddr := vaddr mapping.
You can also add an `UC_HOOK_TLB_FILL` hook to manage the TLB.
The hook is called, when a virtuall address is not cached and Unicorn is in `UC_TLB_VIRTUAL` mode.
You can manual flush the cache with `uc_ctl_flush_tlb`.
