Is it correct that only CM7_0 can be used on the S32K314?

Hello, I have a question after reviewing the S32K314 datasheets (S32K3XXRM, S32K3XXDS).

[Figure 1, in S32K3XXRS Figure 8]

According to the diagram in [Figure 1], there are references to both CM7_0 and CM7_1 in the S32K314.

[Figure 2, in S32K3XXRM Table 26]

However, in [Figure 2], it states that CM7_1 cannot be used on the S32K314.

Which one is correct?

#S32K314

#S32K3XX

#S32K3

#CM7_0

#CM7_1

Re: Is it correct that only CM7_0 can be used on the S32K314?

That is correct, it is not available. The "1" in S32K314 refers to 1 x M7 core, while "4" (such as S32K344) refers to 1 x M7 lockstep core.

Thank you for your reply. Oh, I have an additional question. So the S32K314 series does not have the Lockstep core function?

You can see in [Figure 1], CM7_1 is disabled for S32K314:
