On page 11-127 of the reference manual for xmc4500,
there is a table for RSTSTAT. I cannot find all the information about different reset sources.
What is SWD Reset? PV reset? Thans.

Hello,
PV refers to power validation, which monitors for the core supply voltage VDDC. Power-on reset is triggered if it falls below a specific threshold.
SWD refers to Supply Watchdog, which monitors for the supply voltage VDDP. In this case, power-on reset is triggered if it falls below the reset threshold voltage VOR.
This information can be found from the RM page 11-20.
Sorry that the above is not obvious from the register definitions table. I will feedback accordingly to the relevant colleagues for a future RM improvement.
Thank you for your valuable feedback.
Regards,
Min Wei
