Is data cache being used ?

$

Our ECU is based on Aurix Tricore TC297TF Microcontroller. Core 1 data cache is from 0x6003 C000 to 0x6003DFFF.

I'm trying to figure out if dcache is being used. I'm running my application under control of debugger. I reset the ECU from debugger. I set read / write breakpoint
in data cache address range. Then I execute code. Code doesn't break. Attached is memory dump of this address range.

Is dcache being used or not? Do I need to set some register to enable core 1 dcache?
