看文档中描述的对于ClassA的设备，device number is pseudo-unique，并不是真正的唯一的，并不能满足全球唯一的需求，不知道有没有一个全球唯一的标识？

Because of this specific limitation on the F28335 device, one recommendation is to supplement this 32-bit value with some value that you generate in your process (maybe time stamp or batch serialization). The issue is that some of the fields in the 32-bit unique ID in the F28335 may get duplicated over time (in years) that may break the randomness. The chances of this happening is very small and to alleviate this, you may want to append the 32-bit unique ID with something else from your process.
