I am using MK20DN512ZVM and the sales told me MK20DN512VMD10 is a newer version and send me some samples. then I replace it on my board, but I found the MQX doesn't run! then I analyzed this problem and found out that MCU(MK20DN512VMD10) will reset when run this function.
void PE_low_level_init(void)
{
/* Initialization of the SIM module */

SIM_SOPT6 = (uint32_t)0x00UL; /* Set reset pin filter */

PMC_REGSC &= (uint8_t)~(uint8_t)0x13U;
/* SIM_SCGC4: LLWU=1 */
SIM_SCGC4 |= (uint32_t)0x10000000UL;

LLWU_PE3 = (uint8_t)0x00U;

LLWU_CS = (uint8_t)((LLWU_CS & (uint8_t)~(uint8_t)0x03U) | (uint8_t)0x84U);
}
then I checked the newest ref manual. it confused me much！
is there anyone could help to explain that?
