 @file  cc13x2_cc26x2_app.cmd

 @brief CC26X2R1F and CC13X2R1F3 linker configuration file for TI-RTOS with Code
        Composer Studio.

        Imported Symbols
        Note: Linker defines are located in the CCS IDE project by placing them
        in
        Properties->Build->Linker->Advanced Options->Command File Preprocessing.

        CACHE_AS_RAM:       Disable system cache to be used as GPRAM for
                            additional volatile memory storage.
        FLASH_ROM_BUILD:	If defined, it should be set to 1 or 2 to indicate
                            the ROM version of the device being used. When using
                            Flash-only configuration, this symbol should not be
                            defined.
        ICALL_RAM0_START:   RAM start of BLE stack.
        ICALL_STACK0_START: Flash start of BLE stack.
        PAGE_AlIGN:         Align BLE stack boundary to a page boundary.
                            Aligns to Flash word boundary by default.

 Group: WCS, BTS
 Target Device: cc13x2_26x2
