    Hello Ravi,

    The flash is readable using the method f.m. has suggested or using HWREG(FLASH_ADDRESS) where FLASH_ADDRESS is value between 0x0-0x3FFFC

    Regards

    I could have been more clear, but wanted the OP to think about it. An experienced person is aware of the "asymmetrical" nature of Flash/EEPROM. While erasing/writing requires relatively huge hardware and software efforts (hence the requirement of an API), reading is usually as simple as accessing a certain address. Some background knowledge does never hurt ...
