Assume that the memory display of the ARM Cortex M0+ shows the following content (in Hexa) starting at address SD000 F000 SD000F000: AR 12 00 15 16 17 BC F2 2D A5 DE B3 2C CA 9F B5 2F F9 1. What is address of the last byte ($F9) underlined in red? 2. Write an ARM assembly code that counts the number of negative bytes in the above vector and then store the number of negative values at address $70000000 3. Write an ARM assembly code that counts the number of positive words in the above vector and then store the number of negative values at address $70000000 4. Using a conditional branch instruction write a program that add the two consecutive bytes and store the result as an 8 bit operand at memory starting at sc0000000 e.g. Store (A2 + 12) at address SC0000000 Store (12 +00) at address SC0000001 Store (00 + 015 at address SC0000002 and so on
