Hi Heiko,

Unfortunately, after the discussion with IC, we feel that we can not 
make hardware automatic switch;
The reason for this is that if you accidentally configure all of these 
configurations, the hardware doesn't know which one to choose, and then 
it's not good for our debug, because I don't know which option the 
current hardware is switching to.
So we still maintain the current way, but ask them to write more clearly 
and easily in the TRM file.
