this memory is allocated for the other. But the address
is hold by the controller.
2. Adbd in PC is running. So, the controller receive the
data and write to this memory.
3.The value of this memory is modified by the controller.
This could cause the memory problem.
Solution:
whenever io_data->aio equals 1, the data buffer is from a fixed array.
