For other chips, the upper 16 bits of the register reported the voltage
and the lower 16 bit reported the current. It might possibly be that the
data is now split into multiple registers, but that is impossible to
determine without datasheet and/or additional information. So, sorry,
no, I have no idea. We'll have to wait for someone to reverse engineer
it.
Can you send the contents of the "thm" file ? Maybe we can at least
find the new location of the ccd temperature registers.
