Hi Peter,

In this example, you are using the functional muxing (MSCR registers) to confiure FCCU EOUT_0/1 pins as below. 

   SIUL2.MSCR0_255[112].R = 0x6|0x02000000;     /* FCCU EOUT_0 , ODC push-pul */
   SIUL2.MSCR0_255[115].R = 0x6|0x02000000;     /* FCCU EOUT_1 , ODC push-pul */

However, the recommended way to do this configuration is by DCF clients. -- Chapter 1.2.10 DCF_ERROR0_PAD_SELECT DCF client, MPC5746R Reference Manual Addendum, Rev. 2, 10/2016.  What's more, in the attached (in RM) "IO_Signal_Description and Input_Multiplexing_Tables", ERRORx is not listed as a muxing function which can be assigned to these potential ERROR OUT pins like PH[0] via SIUL2_MSCR registers.

Best Regards
