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?</P><P></P><P>Thank you.</P><P></P><P>BR</P></BODY></HTML> Tue, 13 Dec 2016 08:12:04 GMT miguelportela 2016-12-13T08:12:04Z KM33Z128 boots in VLPR mode https://community.nxp.com/t5/Kinetis-Microcontrollers/KM33Z128-boots-in-VLPR-mode/m-p/604371#M35569 <HTML><HEAD></HEAD><BODY><P>Hello,</P><P></P><P>&nbsp;&nbsp;&nbsp; I am working in a project that uses the microcontroller KM33Z128AM.
