//选择并开启通道
  switch(channel)
  {
case 0:
case 1:
case 2:
case 3:
   SIM_SCGC5 |= SIM_SCGC5_PORTC_MASK;
   PORT_PCR_REG(PORTC_BASE_PTR, channel+1) = PORT_PCR_MUX(4);
   break;
case 4:
case 5:
case 6:
case 7:
   SIM_SCGC5 |= SIM_SCGC5_PORTD_MASK;
   PORT_PCR_REG(PORTD_BASE_PTR, channel) = PORT_PCR_MUX(4);
   break;
default:
   return 0;
  }

怎么配置成A15 ？我做个呼吸灯效果
