Detailed Description

The values of customer configuration (CCFG) settings in flash are determined by ccfg.c and typically a user application does not need to read these CCFG values as they are used mainly during ROM boot and device trimming. However, a subset of the CCFG settings need to be read by application code thus DriverLib provides this API to allow easy read access to these specific settings.

The remaining settings not accessible through this API can of course be read directly at the CCFG addresses in the flash (starting at CCFG_BASE) using the HWREG macro and the provided defines. CCFG settings are documented as part of the register descriptions in the CPU memory map.

Note

CCFG settings are located in flash and should be considered read-only from an application point-of-view.
