Thank you very much for your answer. I seem to have found the problem. Currently, there is no OSC32K external pin in the MCU of the MPC5746C 100MAPBGA, and MC_ME.DRUN_MC.SXOSCON is enabled in the Demo of the SDK, but it does not judge and wait for MC_ME.GS. The .B.S_MTRANS bit is set to 0, so the program jumps to the IVOR1_Handler interrupt when the PIT register is manipulated. It seems that the officially provided Demo Code does not distinguish the 100MAPBGA of the MPC5746C from other Pin packages.
I encountered the same problem as you, but I came up when I initialized the ADC. The program directly enters the IVOR1_Handler interrupt and cannot come out. I want to ask how you solved it.
You look at the model of your MPC5746C, is it 100pin, does the external support 32kHZ crystal oscillator, if it does not support the external 32k crystal oscillator, please do not choose, in addition, which version of SDK do you use?
