About the SRAM locations in KL25Z

When reading the user guide for M0+ ( on page 22 it says that SRAM starts at address 0x2000_0000. However, in the KL25 reference manual, the SRAM is divided in upper and lower sections, where the lower starts at 0x1FFF_F000 (for my 128 KB device). This would put it in the code section, according to the user guide. 


I would just like to understand why this is the case? According to an answer to this question: Why is SRAM split, and what does it mean?, the M0+ does not have separate busses for upper and lower SRAM, so I don't really have to think about it. But even so, why go against the CPU memory model?


Edit: Corrected lower adress.
