Hello everyone. I use MPC5643L and need DSPI module to operate EEPROM to get data read and write. But there is a problem I set periphrals 0 clock as 10MHz. And on the datasheet that it is equals to the dspi Fsys. But I read the real signal on scope and find that the SCK pin clock is 500K not 10MHz. I cannot figure it out.

 

Thank you for your help!!!
