CC1101有时不能发码，哪位大神帮忙解析下，谢谢！

应用：MSP430控制CC1101发码，由外部电源触发电源给CC1101供电2S时间，让CC1101发4条相同协议的码，有时不能发码，（已确定触发电源供电正常）

初始化和发码代码如下：

/*********************************************************

    P2SEL &= ~(TI_CC_CSn_PIN); //TI_CC_GDO0_PIN+    P2SEL2 &= ~(TI_CC_CSn_PIN); //TI_CC_GDO0_PIN+    TI_CC_GDO0_PxDIR &= ~TI_CC_GDO0_PIN;    TI_CC_GDO0_PxIES &= ~ TI_CC_GDO0_PIN;    TI_CC_GDO0_PxIFG &= ~TI_CC_GDO0_PIN; // Clear flag
    TI_CC_GDO0_PxIE &= ~ TI_CC_GDO0_PIN;    TI_CC_GDO0_PxREN |= TI_CC_GDO0_PIN;}
