RASC图形化配置

输出模式：

输入模式：

配置选项：

配置项	取值/描述
Mode	l "Input mode"（输入模式）l "Output mode(Initial Low)"（输出模式，初始电平为低）l "Output mode(Initial High)"（输出模式，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)
