CC2640如何设置上升沿触发和下降沿触发？？

请问你用什么模块?

ADXL362 的中断处理，SPI通信。

嗯嗯明白了，还有一个问题，我看咱的中断（灯示例）没有开启中断和清除中断的代码？？？
示例代码如下所示：
PIN_Config ADXL362PinTable[] = {
ADXL362_INT | PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_NEGEDGE,
PIN_TERMINATE
};
ADXL362PinHandle = PIN_open(&ADXL362PinState, ADXL362PinTable);

需要额外加开启中断和清楚中断的代码吗？具体代码是什么呢？

/** @brief Control interrupt enable and edge for pin
 *
 *  @param handle  Handle provided by previous call to PIN_open()
 *  @param pinCfg  #PIN_Config entry identifying pin ID and relevant pin
 *                 configuration as combinations of:
 *                 - #PIN_IRQ_DIS      (default)
 *                 - #PIN_IRQ_POSEDGE
 *                 - #PIN_IRQ_NEGEDGE
 *                 - #PIN_IRQ_BOTHEDGES
 *  @return #PIN_SUCCESS if successful, else error code
 *  @note Any pending interrupts on pins that have not had interrupt enabled
 *        will be cleared when enabling interrupts
 *  @par Usage
 *       @code
 *       PIN_setInterrupt(hPins, PIN_ID(8)|PIN_IRQ_POSEDGE);
 *       @endcode
 */
extern PIN_Status PIN_setInterrupt(PIN_Handle handle, PIN_Config pinCfg);

例程是直接在PIN_Config 里设置了

两种方式都可以，你自己选择
