Exercise 1 Figure 1 below shows the block diagram of a processor Integrated Circuit (IC). AVR CPU Oscillator 40H Crystal wேiintator Flash M 16 KB MCU C And Timing SRAM 1 KB EEPROM 5125 Iepet/Outpet Ports Interface PORTA PORTE PORT PORT Justification; ....... Tweew Counters d Timer USART SPI 1- Is the processor a microprocessor or microcontroller? TWI ISP Interrat Figure 1 The processor is: Microprocessor / Microcontroller ADC Justify your answer. 2- How many address lines are there required for the Flash Memory? There are ..address lines for the Flash Memory 3- How many address lines are there required for the the SRAM memory? There are address lines for the SRAM memory 4- The processor is a 16 bits processor. Does the processor require more instructions than the Cortex MO+ processor to perform 32 bits additions when the operands are stored in CPU internal registers? Justify your answer./nThe processor requires more clock cycles: Justification; 5- The Flash memory is a kind of RAM memory: True/False 6- Which of the following address ranges are possible for the Flash memory? Select ALL applicable. a- From Ox100 to 0x1FFF b- From 0x3000 to 0x3FFFFF c- From Ox5000 to 0x8FFF d- None of the above True/False 7- The Booting address of the processor is 0x2FFF. Which of the following address ranges can't be allocated to the RAM memory? Select ALL applicable. a- 0x2000 to 0x23FF b- 0x1000 to 0x13FF c- 0x000 to 0x3FF d- All of the above e- None of the above 8- What can be true about the Program Counter Register of this processor? a- It can be 4 bits width b- It can be 8 bits width c- It can be 9 bits width d- None of the above 9- Is it possible to interface the processor to an analog sensor? Select: Possible/Not possible. 10- The CPU has a multiplier that accepts two 16 bits operands and store the results into 24 bits special function register. For the multiplication of two unsigned numbers A and B, what would be the maximal value of B to avoid an overflow if A = 2¹4? (1 Mark)
