CAUTION: This configuration
               takes effect immediately. Therefore, users must ensure that no access is performed on
               a SRAM sub-block which is switched OFF. When a SRAM sub-block is switched from OFF to
               ON state, a delay of 1 µs is required before re-accessing it.
