the WAI (whoami) register is writeable. Not only is it writeable, but the written value is persistent across a power cycle. You have to remove power for about 30s for it to finally go back to the right default value of 0x10 this makes using WAI as a test for finding a IST8310 problematic. The best we can do is send a soft reset which will reset it to default for us to then check
