I am using mpc5748g for SPI transmission.

But when i am transmitting only 16 bits of data,

The same data is repeated 5 times.

What might be the issue or any configuration issues. Please let me know

Hi,

 

most probably you incorrectly use PUSH register, you should write command+data word into PUSHR.

You can refer to simple SPI demo example within S32 Design Studio.
