What is the ralationship between "valotile" and cache of S32R274

[Durant-Harden-Irving]

Hello,

I define a global variable with valotile(cache is enable)，and write value twice：

CASE 1：

volatile unsigned int cache_Test;  

cache_Test = 0x100;    //0x100 is written in ram and cache

cache_Test = 0x200;    //0x200 is written in cache while in ram the value is 0x100

CASE 2：

volatile unsigned int cache_Test;  

cache_Test = 0x100;    //not mapping to cache because of valotie; 0x100 is only written in ram.

cache_Test = 0x200;    //0x200 is only written in ram.

My question: which case occur / which case is correct  in s32r274?

Thanks!
