现象

客户工程：FM33LC046N, PD10配置为OUTPUT，进行复位操作时，封装视图上所有引脚都被复位了。

分析

后台抛出异常

关联代码

        if PinConfig and (mode in [IO_INPUT, IO_OUTPUT, IO_RESET]):
            if pin_obj.getPinAssociated() in ["RCC", "CMU"] and pin_obj.config is not None:
                # 如果外设配置中XTHF、XTLF开启，时钟树中选用了他们之一
                arr = pin_obj.config.split("_")
                peri_name = arr[0]
                func_name = arr[1]
                clockObj = ClockTreeHelper(self.project_id)
                if func_name in ["XTHI", "XTHO", "XT32KI", "XT32KO"] and clockObj.ClockIsUsed(func_name):
                    return { "ret": False, "message": "%s所开启的外部时钟源已被时钟树选用,无法被复位,请调整时钟树后再试." % instance }
                else:
                    # 同步到时钟树
                    clockObj.Close_XTLF_XTHF(func_name) 

原因

PD10并未配置为XTLF，但pin_obj.getPinAssociated() 居然得到了RCC对象，这可能是历史工程造成的。

解决方案

添加try语句捕获异常不处理；
