11) How would you program an ACD with the fastest conversion time and lowest accuracy? a. ADSCRA = Ox87 b. Write a 0 to MUX3, 0 to MUX2,0 to MUX1, and 0 to MUXO C. Write a 0 to ADPS2, 0 to ADPS1, and 0 to ADPSO d. Write a 1 to REFS1, 0 to REFSO 12) For an ATmega328P with an 8MHZ oscillator frequency, determine the correct values for TCCRZA, TCCR2B, and OCR2A in order to have a 22.4 ms timer operating in CTC mode. a. TCCR2A = Ob00000010, TCCR28 = Ox06, OCR2A = 250 b. TCCR2A = Ob00000010, TCCR2B = 0x07, OCR2A = 175 %3D %3D c. TCCR2A = Ob00000010, TCCR28 = 0x06, OCR2A = 185 d. TCCR2A = Ob00000110, TCCR2B = Ox07, OCR2A = 255 %3D 13) How would you select an ADC prescaler of 32? a. ADSCRA = Ox85 b. Write a 0 to MUX3, 0 to MUX2, 1 to MUX1, and 1 to MUXO Write a 1 to REFS1, 0 to REFSO d. ADSCRA = Ox87 C. 14) Which Timer/Counter does not have access to the Timer/Counter Interrupt Mask Register? a. Timer 0 b. Timer 1 C. Timer 2 d. All of them have access to this register
