[−]Module cortex_a::regs::SCTLR_EL1::C
Cacheability control, for data accesses.
0 All data access to Normal memory from EL0 and EL1, and all Normal memory accesses to the EL1&0 stage 1 translation tables, are Non-cacheable for all levels of data and unified cache.
1 This control has no effect on the Cacheability of:
- Data access to Normal memory from EL0 and EL1.
- Normal memory accesses to the EL1&0 stage 1 translation tables.
When the value of the HCR_EL2.DC bit is 1, the PE ignores SCLTR.C. This means that Non-secure EL0 and Non-secure EL1 data accesses to Normal memory are Cacheable.
When ARMv8.1-VHE is implemented, and the value of HCR_EL2.{E2H, TGE} is {1, 1}, this bit has no effect on the PE.
When this register has an architecturally-defined reset value, this field resets to 0.
