State the voltages you expect to appear on PORTB pins(7 to 0) in each of the following cases: portb-0x47; portb- 47 portb 1lb portb 101 portb= 0b01010101 11. If a variable called my counter is declared as follows:- unsigned char my counter, How many bytes of RAM will the variable occupy? . What is the minimum and maximum values the variable could have? 12. A variable called count has the value 20. What value does it have after the following statement has been executed? count count>>2 13. There is a difference between logical operators(, ,&&) and bitwise operators (I.&).What values does portb have after the following statements are executed. portb 0x01 0x06; portb 0x01 0x06
