Note : Referencing the external components should be avoided in most cases. Only in unavoidable circumstance external components should be referred. Developer should track the references.
Global Functions(Non RTE) to be provided to Integration Project
DtsInin - To be defined as a trusted function as the DTS Channel master registers need to be configured in the supervisor mode.
DtsClnUp - To be defined as a trusted function as the DTS registers are being re-configured in the supervisor mode to avoid access protection violation
CodFlsSngBitEcc – Single bit code flash ECC error handler call back function provided to the MCAL driver

Da Vinci Parameter Configuration Changes
| Parameter | Notes | SWC |
| /Nexteer/FlsMem/FlashCRCRegnConfig/ StartAddress | Configured with “FlashCRCRegnConfig” Each Flash region(for eg:- Boot, App, Cal1) has a start address where the code resides on the flash | FlsMem |
| /Nexteer/FlsMem/FlashCRCRegnConfig/Length | Configured with “FlashCRCRegnConfig” Each Flash region has a length defined for the region | FlsMem |
| /Nexteer/FlsMem/FlashCRCRegnConfig/PredefinedCrcAddress | Configured with “FlashCRCRegnConfig” Each Flash region has a PredefinedCrcAddress defined for the region which is used by the CCT tool for storing the checksum on the flash and serves as the reference location to retrieve the pre calculated CRC and do a comparison with calculated CRC | FlsMem |
/Renesas/EcucDefs_Mcu/Mcu/McuModuleConfiguration /McuEcmErrorSourcesCfg/McuEcmErrorSource36 | Call back function name is “CodFlsSngBitEcc”. Refer the CM104A Integration manual for the configuration of the error source. (Type of the error, classification of the error eg FENMI or EI information) . |

Runnable Scheduling
This section specifies the required runnable scheduling.
| Init | Scheduling Requirements | Trigger |
| FlsMemInit1 | None | Once At Init (RTE) |
| FlsMemInit2 | Non-RTE Init, Called in Startup Sequence* | Function call in Startup Sequence |
| Runnable | Scheduling Requirements | Trigger |
| FlsMemPer2 | None | 100ms(RTE) |
*“FlsMemInit2” shall schedule after OS Start – Refer CM100A Start up sequence.
PEG shall be configured before “FlsMemInit2”.
CrcHw Init shall be scheduled before “FlsMemInit2”.
Memory Map REQUIREMENTS
Mapping

Appendix
The current implementation of the Flash Config Blocks in the configurator accepts values for all the parameters. Future implementation shall be targeted with parameters being able to also accept linker symbols
