In Referece Manual, there is 12 K RAM in S12ZVCA192, and adress is 0x00_1000 - 0x00_3FFF (from Table 1-3). But in mc9s12zvc192.prm file which is generated by CW10.6, it is

RAM           = READ_WRITE  0x001000 TO 0x002FFF;

Only 8k RAM. If change 0x002FFF to 0x003FFF in prm and using the address from 0x2fff to 0x3fff, the code will run away. Why RAM is 0x1000 to 0x2fff and only 8k? How to use other 4k RAM?
