我想把按键SW1、SW2端口改成P1_1，所以就把一些原来的端口配置都改成了P1口和BIT(1),其他的地方都没有变，更改的程序如下所示：
/* CPU port interrupt */
#define HAL_KEY_CPU_PORT_1_IF P1IF
#define HAL_KEY_CPU_PORT_2_IF P2IF
#if defined ( CC2540_MINIDK )||( WEBEE_BOARD )
/* SW_1 is at P0.0 */
#define HAL_KEY_SW_1_PORT P1
#define HAL_KEY_SW_1_BIT BV(0)
#define HAL_KEY_SW_1_SEL P1SEL
#define HAL_KEY_SW_1_DIR P1DIR
/* SW_2 is at P0.1 */
#define HAL_KEY_SW_2_PORT P1
#define HAL_KEY_SW_2_BIT BV(1)
#define HAL_KEY_SW_2_SEL P1SEL
#define HAL_KEY_SW_2_DIR P1DIR
#define HAL_KEY_SW_1_IEN IEN1 /* CPU interrupt mask register */
#define HAL_KEY_SW_1_ICTL P1IEN /* Port Interrupt Control register */
#define HAL_KEY_SW_1_ICTLBIT BV(0) /* P0IEN - P0.0 enable/disable bit */
#define HAL_KEY_SW_1_IENBIT BV(5) /* Mask bit for all of Port_0 */
#define HAL_KEY_SW_1_PXIFG P1IFG /* Interrupt flag at source */
#define HAL_KEY_SW_2_IEN IEN1 /* CPU interrupt mask register */
#define HAL_KEY_SW_2_ICTL P1IEN /* Port Interrupt Control register */
#define HAL_KEY_SW_2_ICTLBIT BV(1) /* P0IEN - P0.1 enable/disable bit */
#define HAL_KEY_SW_2_IENBIT BV(5) /* Mask bit for all of Port_0 */
#define HAL_KEY_SW_2_PXIFG P1IFG /* Interrupt flag at source */
#define HAL_KEY_SW_1_EDGEBIT BV(0)
PICTL |= HAL_KEY_SW_1_EDGEBIT; /* Set the edge bit to set falling edge to give int */
是不是这样就可以了？但是我测试了一下，按下按键没什么反应，这个是怎么回事呢？求大神指点下，谢谢了
