Linflex registers error in MPC5746R.h

It seems that I've found another error in the S32DS v1.2 MPC5746R.h.

Referring to table 54-19 in the MPC5746RRM.pdf, the DMATXDE register is often at offset 0x58. The supplied header file always has it at offset 0x98. This results in a Machine Exception (IVOR1) when you try to write it.

I found this on Linflex 2.

e.g.

    LINFlexD_2_DMATXE = 0;
 1048ece:    70 ff e7 e9     e_lis   r7,65513
 1048ed2:    48 06           se_li   r6,0
 1048ed4:    54 c7 00 98     e_stw   r6,152(r7)

i.e. 152(r7) = FFE90098 which generates an illegal write. It should be FFE90058

Hello James,

I am really sorry for long delay. I have already created report for application team which points to mistakes in header file. I will let you know as soon as I get any feedback from application team.

Regards,

Martin
