Section 8. Operation Table 86. CR6 Main Memory Use Static Memory Comments Operational memory used by the operating system. Rebuilt at power-up, program re-compile, and watchdog events. Operating Settings and Properties "Keep" (p. 499) memory. Stores settings such as PakBus address, station name, beacon intervals, neighbor lists, etc. Also stores dynamic properties such as the routing table, communication timeouts, etc. CRBasic Program Operating Memory Variables & Constants Stores the currently compiled and running user program. This sector is rebuilt on power-up, recompile, and watchdog events. Stores variables used by the CRBasic program. These values may persist through power-up, recompile, and watchdog events if the PreserveVariables instruction is in the running program. Final-Data Memory Stores data. Fills memory remaining after all other demands are satisfied. Configurable as ring or fill-and-stop memory. Compile error occurs if insufficient memory is available for user-allocated data tables. Given lowest priority in SRAM memory allocation. Communication Memory 1 Communication Memory 2 Construction and temporary storage of PakBus packets. Constructed Routing Table: list of known nodes and routes to nodes. Routers use more space than leaf nodes because routes to neighbors must be remembered. Increasing the PakBusNodes field in the Status table will increase this allocation. USR: drive
