If you're doing this manually, nrf_ic_info_get gets register 0xF0000FE8 , and checks to see if the last byte is 0x1_ (rev 1), 0x4_ (rev 2), or 0x7_ , 0x8_ , or 0x9_ (rev 3) (where underscore means any…

The HWID 0x84 is not in the compatibility matrix. Are all HWID values in the compatibility matrix?
