Device memory layout can be verified by : Only Downloading code and then verify memory By Linker By Compiler None of the above 2. Which of the following is True for STM32 ? If you halt CPU execution, RTC will also stop RTC is separate IP block and will continue to run even after CPU is halted We can’t halt CPU when RTC is running 3. Boot configuration in STM32 is done by : Hardware only Hardware and/or option bytes programming Factory programmed None of the above 4. LSE(Low Speed External) clock in STM32 Nucleo board : Enabled by default Needs to be enabled by RCC->BDCR register None of the above 5. Block Started by Symbol is : Intitialized data segment Un-initialized data segment Code segment Not related to Embedded 6. One can create STM32 Nucleo-L4R5ZI device header file with the help of STM32L4R5ZI datasheet and STM32L4 family Reference manual : True False 7. APB in STM32 stands for : Application Process Bus Advanced Peripheral Bus None of the above 8. STM32 device can fetch instruction from : Only Flash Only SRAM Flash or SRAM Only from Bootloader 9. Which of the following statements are True to program RTC? Enable PWR block Disable RTC protection Boot from default factory program in system memory 10. What is the purpose of external crystal for LSE(Low Speed External) in STM32 Nucleo board ? It is required to sync-up LSE(Low Speed Internal) RTC can’t work without LSE . It is required for STM32 Peripherals Crystal is much better in terms of accuracy over temperature range and less jitter Loading … Question 1 of 10 Job Assistance Related
