gpio外部中断exti_isr

[Mars]

初始化
__SYSTEM_GPIO_CLK_ENABLE();
// EXTI interrupt
GPIO_Handle.Pin = GPIO_PIN_0|GPIO_PIN_1;
GPIO_Handle.Mode = GPIO_MODE_EXTI_IT_FALLING;
GPIO_Handle.Pull = GPIO_PULLUP;

gpio_init(GPIO_B, &GPIO_Handle);

exti_interrupt_enable(EXTI_LINE8_PB0);
exti_interrupt_enable(EXTI_LINE9_PB1);
NVIC_EnableIRQ(GPIO_IRQn);

识别中断
void exti_isr(void)
{
if (exti_get_LineStatus(EXTI_LINE8_PB0))
{
exti_clear_LineStatus(EXTI_LINE8_PB0);
// cpu_to_pmu_ctrl();
// sleep_state = 0;
// system_sleep_enable();
co_printf("this is exti line 8 \r\n");
}

if (exti_get_LineStatus(EXTI_LINE9_PB1))
{
	exti_clear_LineStatus(EXTI_LINE9_PB1);

// cpu_to_pmu_ctrl();
// sleep_state = 0;
// system_sleep_enable();
co_printf("this is exti line 9 \r\n");
}
}

这是遇到啥问题，是不是初始化下降沿触发，但上升沿信号也会触发中断

外部中断exti使用是有例程的，参考\examples\none_evm\peripheral_demo\gpio
