these code are used to initialize the RAM with 32-bit writes.
please refer to S32K-RM Chapter 32.5
32.5 Initialization / application information
It is essential that each memory address be written to a known value before it is read.
This includes reads generated from the read/modify/write operation which occurs when a
write transfer of less than 32 bits or unaligned write is requested (see Less than 32-bit
writes). Without writing an address to a known value first, a read from this address will
most likely generate an ECC multiple error.
for your question:
you can take a look at the belowing two routines in the picture,
