MCU crashes when writing CSE registers

[WUXIE]

Hi Team NXP,

After Mode,PLL initialled，when I try to write CSE registers，MCU crashes，Error interrupt is "IVOR1trap: b IVOR1trap /* Machine check / (NMI) interrupt handler */"。the code is as follows:

CSE.CR.B.DIV = 29;                // MCU STOP here!
CSE.CMD.R= CSE_INIT_CSE;
while (CSE.SR.B.BSY ==1){} /*wait until CSE is idle*/
CSE.P1.R = (vuint32_t)&get_id_challenge; /* input challenge value*/
CSE.P2.R = (vuint32_t)&GET_ID_UID; /* output UID*/
CSE.P3.R = 0;
CSE.P4.R = (vuint32_t)&UID_MAC; /* output challenge response */
CSE.CMD.R= CSE_GET_ID;

thanks advanced !
