6.2.4
As noted previously, depending on the configuration defined by the RAMBAR, instruction fetch
and operand read accesses may be sent to the SRAM and cache simultaneously. If the access is
mapped to the SRAM module, it sources the read data and the unified cache access is discarded.
If the SRAM is used only for data operands, setting the ASn bits associated with instruction fetches
can decrease power dissipation. Additionally, if the SRAM contains only instructions, masking
operand accesses can reduce power dissipation.
