     I want to use the IIC fucntion of mcu s32K144,but I didn't want to use the process expert code  to generate IIC function code.


      After I configured these register,and initial the IIC register.I write the 0x04 command and one byte data to register MTDR, according to IIC communication protocal, then I should waite for transmission to end ,and check the ACK of slave device,for the ACK I check all register,and didn't have the ACK flag,so How can I judge the success of this send and start sending the next byte of data?
