we now use S32DS to program SPI interface of SPC5744. MPC5744P PRM shows the reset value of SPI_0.MCR.HALT is "1" . But when I try to debug, after reset of CPU, the HALT bit of Register SPI0.MCR is "0" and cannot set to "1" by software. The MCU has excuted no code before. I upload a picture about this problem, please help me, that's really confusing!
