This function sets the lock lock[index] to write the locked DMA region at the moment of the unlock. The data sent locally will be treated as count elements of the format and will be stored starting at address. This function allows the system to use the same message to release the lock and to write its related data.
This function must be called after a0SetLockDMARegionPart() or a0SetLockDMARegion() and before a0Unlock() or a0IUnlock().
On return of this function, the variable pointed by lock contains a lock descriptor to write the given data.
