Is it possible to increase CACHE_L1D beyond 32KB?

Hi,

The following is from my memory map file. I wonder if i can increase CACHE_L1D to 48KB while reducing the L1DSRAM from 48KB to 32KB in the linker command file? I looked at the myApp.tcf file, in the system->Global Settings->64PLUS->64P L1DCFG setting, the maximum size for L1DCFG is 32KB. It looks like i can only split this 80KB of SRAM to 32KB of L1D_CACHE and 48KB of L1DSRAM. Is this correct?

Thanks,

Zhao
