Looks like the DC code can't correctly take care of the difference between CZ and Tonga. Harry how should we handle this? Either not set the bit on older hardware or fix DC to just ignore it there? To be honest I would prefer not to set a bit at all and just always program the relevant bits on hardware which supports this. Regards, Christian.
