 just a brief reply: the CPU has built-in BCH error correcting of up
to 64 bits per 512 or 1024 bytes block, can provide an error
correction report, and also appears to have a randomiser if you need

 this is very strange not least because it appears that someone has
really really thought about this stuff... but then it gets piped
through a china factory supply line where absolutely nobody knows or
even cares what's going on.
