CC2530疑似BUG,采样内部VDD/3电压会触发P0.0中断!

Other Parts Discussed in Thread: CC2530

TI工程师:

    HI,在我的项目中要用到P0.0,P0.1,P0.4,,P0.5中断,下降沿触发。平时处于休眠状态,在这几个外部中断发生时我用内部的1.15V做参考电压来检测内部的VDD/3 ,在产生P0.0中断时一切都是正常的,但是当P0.1,P0.4,P0.5产生中断并保持低电平时,在读完ADC值后就触发P0.0中断这时P0IFG = 0x01,如果我注释掉ad = HalAdcRead(HAL_ADC_CHN_VDD3,HAL_ADC_RESOLUTION_14),就不会发生这个问题。

我在E2E论坛上搜索,发现有人发现了和我上面描述的问类似的情况:http://e2e.ti.com/support/low_power_rf/f/158/p/280178/980604.aspx#980604

所以想请问TI的工程师,这是不是一个CC2530硬件BUG呢,如何避免?
