how to setup ADC temperature measurement_MPC5744P FOC motor control

NXP expert,

I am working on PMSM motor control application using MPC5744P. motor three phase current and dc bus voltage ADC measurement for FOC is done under CTU control mode every 100us(PWM Mater reload trigger CTU, CTU delayT0 trigger ADC to do the dual mode measurement). I have many temperatures need to be measured every 100ms, would you please suggest what is the best way to implement CTU and ADC for the temperature measurement?( according to MPC5744P RM, once in CTU mode the ADC normal mode request will be discarded.)

Thank you very much.
