KM33Z128 boots in VLPR mode

Question asked by Miguel Portela on Dec 13, 2016

Hello,

 

    I am working in a project that uses the microcontroller KM33Z128AM. I realized that some chips are booting randomly in VLPR mode. After that, when configuring the clock, the devices performs a reset. The device then enters in a infinite loop of resets. The bit EXE_MODE in FTFL_OPT register is zero. Therefore, I think the microcontroller should be always exit from reset in RUN mode. In which other situation could the device boot in VLPR mode?

 

Thank you.
