SOC的特性：外部GPIO中断

Required Methods§

source

fn eirq_req( &self, port: GpioPort, pinmsk: XwSq, eirq: XwId, flag: EirqFlag, isr: fn(_: &Self, _: XwId), ) -> XwEr

申请外部中断

§参数说明
  • port: GPIO端口，取值 GpioPort
  • pinmsk: GPIO引脚掩码，每一位代表一个引脚，可通过 pin!() 宏生成
  • eirq: 外部中断号
  • flag: 外部中断标志，取值 EirqFlag 的常量组合
  • isr: 中断函数
§错误码
source

fn eirq_rls(&self, port: GpioPort, pinmsk: XwSq, eirq: XwId) -> XwEr

释放外部中断

§参数说明
  • port: GPIO端口，取值 GpioPort
  • pinmsk: GPIO引脚掩码，每一位代表一个引脚，可通过 pin!() 宏生成
  • eirq: 外部中断号
§错误码
