RAM blocks which are dedicated to each subsystem and are accessible only to its CPU and CLA, are called local shared RAMs (LSx RAMs).
All LSx RAM blocks have parity. These memories are secure and have the access protection (CPU write/CPU fetch) feature.
By default, these memories are dedicated only to the CPU, and the user could choose to share these memories with the CLA by configuring the MSEL_LSx bit field in the LSxMSEL registers appropriately (see Table 6-6).
