Hi, I would like to get my chips temperature sensor working to get the chips temperature without using the onboard I2C temperature sensor, by looking at the documentation, I should be able to use parameters starting at address 0x0800080. I am able to read all of the values here besides the VPL, VPH, VCL and VCH addresses, when I try to read them I read 0xFFFF for all four of them. I don't believe this is correct, is there something I need to run to have these calibration parameters be set?

Temperature parameters begin at 0x00800100, not 0x00800080. I see valid-looking data between 0x00800100 and 0x0080010b on a SAMD51.

 

However, as I mentioned in another recent thread, the errata sheet says the SAM D5x/E5x temperature sensors are not supported.
