假设希望将TimerA0设置为选择SMCLK时钟源，且工作在连续模式，下列控制字正确且最合理的是：
A: TA0CTL = TIMER_A_CTL_SSEL__SMCLK | TIMER_A_CTL_MC__CONTINUOUS
B: TA0CTL &= TIMER_A_CTL_SSEL__SMCLK & TIMER_A_CTL_MC__CONTINUOUS
C: TA0CTL += TIMER_A_CTL_SSEL__SMCLK + TIMER_A_CTL_MC__CONTINUOUS
D: TA0CTL |= TIMER_A_CTL_SSEL__SMCLK & TIMER_A_CTL_MC__CONTINUOUS
A: TA0CTL = TIMER_A_CTL_SSEL__SMCLK | TIMER_A_CTL_MC__CONTINUOUS
B: TA0CTL &= TIMER_A_CTL_SSEL__SMCLK & TIMER_A_CTL_MC__CONTINUOUS
C: TA0CTL += TIMER_A_CTL_SSEL__SMCLK + TIMER_A_CTL_MC__CONTINUOUS
D: TA0CTL |= TIMER_A_CTL_SSEL__SMCLK & TIMER_A_CTL_MC__CONTINUOUS
举一反三
