I am using s32k148  microcontroller for programming two SPI and one UART module. first i debug the example code LPSPI_s32k144 and LPUART_s32k144 for SPI and uart saperately and it worked .but when i combine code it stucked at b     default ISR. I already included the lpspi and lpuart C and header file.using break points i found that after following code line it goes into default ISR

         LPSPI1->IER   = 0x00000000; 

and is showing following screen

If default ISR was happen once you access register of LPSPI1, then you may need to check the value of PCC_LPSPI1.
