    How to use the SAR ADC's injection channel for die temperature?


      I'd like to sneak in a temperature measurement from time to time, while the ADC is usually busy scanning 4 differential channels using SARSEQ. From the PSoC63 register TRM I gathered that exactly this use case is suitable for the ADC's injection channel. However, the architecture TRM is pretty silent about it (I have document 002-18176 Rev. *J).


      Also there are some screenshots of example projects that show a die temperature sensor component in the schematic. I can't find it in PSoC Creator's component catalog, but the resource meter shows it as unused - so it's there in Creator's internals in some way. How do I add the temperature measurement to the schematic (do I need it there in the first place)?
