MSPM0G3519: G3519 Vref and TempSensor Question

Jason Chen

Part Number: MSPM0G3519
Other Parts Discussed in Thread: SYSCONFIG

MCAL version: MCAL_MSPM0_00.02.05.00 

A 1uF CAP is connected between Pin PA23 and GND(For intVREF), and I'm already configured intVREF to 1V4.

My question:

  1. How can I read intVREF value though ADC channnel. If it's possible, which ADC channel should I select.
  2. How can I read MCU Temperature though ADC channnel. If it's possible, which ADC channel should I select.

    The internal temp sensor is routed to ADC0-channel 11. You will need to also check the disable channel 11 pin in the ADC tab in sysconfig, but after that, you can read the temp value via the ADC in your main program. I am not sure you can read the internal vref pin unfortunately, I am not finding anything in the datasheet/TRM that indicates that an ADC channel can be routed to the VREF itself. Hope this helps!
