| destp | Pointer to the swap destination |
Value stored in the swap destination immediately prior to the swap.
This function swaps setData and the data stored at *destp. This function implements spinlock to exclusively control resources that are shared between processors or modules. MI_SwapByte() swaps byte data. MI_SwapWord() swaps word data.
Note that byte access to the main memory is possible only via cache in the TEG environment. Therefore, MI_SwapWord() should be used for main memory.
This swaps using the ARM instructions swp or swpb.
None.
