tion [4]: Answer the following questions (T/F) [15 marks] 1. ( ) C code is easier to modify and update compared to assembly code. 2. ( ) The maximum number can be reached using "char" Data type is +255. 3. ( ) To toggle a certain bit, it could be achieved by XOR-ing it with one 4. ( ) In AVR microcontrollers, Timer2 is 8-bit timer 5. ( ) In order to enable an interrupt, the global interrupt enable should be set in addition to the interrupt enable for that particular interrupt. 6. ( ) In processors, generally we have two sources of interrupts Hardware and software. 7. ( ) When the interrupt is served, the current PC should be saved in the stack memory 8. ( ) An interrupt with a lower 'Vector No' has a higher priority. 9. ( ) A clock is essential in asynchronous communication to send and receive data. 10.( ) For 7O, each symbol (byte) will be transmitted as a frame of 11 bits. 11.( ) SPI is asynchronous protocol while UART is not. 12.( ) The main component of the SPI is the shift register. 13.( ) The sensor's output is a analog signal. 14. ( ) For 16MHz AVR frequency, 2 prescalar is required to derive the ADC frequency. 15. ( For 8-bit ADC, if the Vref=5V and the input is 4.1V, the output will be 11010111
