I am debuging the MC33774 program and use Application mode to measure temperature and voltage. There is a MCAL package for us and I call the function in this package. I found the function Bcc_774a_MSR_SetMode has been called twice in the example code which was given by NXP. Why this register should be written twice? And now there is a really weird problem that MC33774 always gave the invalid values for AIN4~AIN7 measurement results. But the VC and AIN0~AIN3 measurement results are OK which are belong to primary digital module. I tried to read period mode measurement results registers and application mode measurement results registers ,all the datas are invalidate(0x8000). I am wondering if there is someone who can help me resolve this problem.
And I upload the SPI data that I recorded when MC33774 is working in the attach file.
Please help me solve this problem.
Thank you
