配置选项：

配置项取值/描述
Model “Input mode”（输入模式）l “Output mode(Initial Low)”（输出模式࿰c;初始电平为低）l “Output mode(Initial High)”（输出模式࿰c;初始电平为高）
Pull up（上拉电阻）l “None”（禁止内部上拉）l “input pull-up”（使能内部上拉）当引脚被配置为Output mode时无法设置Pull up参数
IRQ（中断）l “None”（不使用中断）l “IRQ10”（使用中断）
Output type（输出类型）l “CMOS”l “n-ch open drain”（开漏）当引脚被配置为Input mode时无法设置本参数
Symbolic Name#define LED (BSP_IO_PORT_04_PIN_00)
