    Hello Venu,
    1. FLASHMEM_BASE(0x00000000) is where the internal Flash memory starts and FLASH_BASE (0x40030000) is where the flash controller is located. The Flash end address is FLASHMEM_BASE + FLASH_SIZE. FLASH_SIZE is 32/64/128Kb depending on your chip.

    2. The number for writes are limited, but the number is very high. Please refer to this thread. e2e.ti.com/.../444765

    3. Flash memory is partitioned into sectors. Each sector is 2048 words. The whole sector needs to be erased and programmed when writing new data.
    Please refer to this for documentation

    C:\ti\tirtos_cc13xx_cc26xx_2_21_00_06\products\cc13xxware_2_04_03_17272\driverlib\flash.c/h files for the API.
