stm8s PA2引脚怎么配置为中断输入？

发表于 2016-7-11 16:11

我是这样配置的，怎么还是没有进入中断函数？
PA_CR1 |=0b00000110; PA_CR2 &=0b00000110; PA_DDR |=0b00000010;
EXTI_CR1=0x03;
@far @interrupt void RS485_RX_Interrupt(void)
{

if(RS485RX)
      {
   RX |=0x80;
      }
   RX>>1;

}
{0x82, (interrupt_handler_t)_stext}, /* reset */
      {0x82, NonHandledInterrupt}, /* trap  */
      {0x82, NonHandledInterrupt}, /* irq0  */
      {0x82, NonHandledInterrupt}, /* irq1  */
      {0x82, NonHandledInterrupt}, /* irq2  */
      {0x82, RS485_RX_Interrupt}, /* irq3  */
      {0x82, NonHandledInterrupt}, /* irq4  */
      {0x82, NonHandledInterrupt}, /* irq5  */
