I work on an Aurix microcontroller, that he has some type of memory can be cacheable and non cachable,
the addresses are cacheable by default,
and I want to run my code in the non-cacheable LMU_SRAM, so I want to change the address of LMU_SRAM to be non-cacheable,
it is cachable by default in the range 0x9000.0000 ... 0x9000.F777 and I want to change the address so that it is in the range non-cacheable which is between 0xB000.0000 ... 0xB000.F777.
I need a macro that allows to change the first bit 9 to B so that it is not cachable.

could help me please.
