MCP9600 Cold Junction and ADC Resolution

I am using an MCP9600 in a temperature-based dispensing project, and I want to be able to set or confirm the setting of the cold junction and ADC resolutions. I am in a situation where I can see the bitfields for setting the resolutions (lines 84 and 88) in the file init.py in the distribution package, but I can not work out how to adjust these bitfields? I can see the definition of functions to get the hot junction temperature and set the thermocouple type etc, but I am not experienced enough to work out how to do this for the resolutions?
I am quite inexperienced and would appreciate any help or ideas?

Thanks!
