TMS570LC4357: GIO复用问题

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

我使用的TMS570LC4357开发板,板上的LED2接在GIOB_6,查看原理图得知物理引脚为J2,其中GIOB_6还有个复用引脚为R3。在HALCOGEN中配置J2为GIOB_6引脚,main函数控制GIOB_6输出脉冲,LED2正常闪烁。

                  

新建工程,在HALCOGEN中,配置R3为GIOB_6引脚。结果LED2依然可以闪烁。理论上LED2接在J2引脚上,配置R3为GIOB_6后,LED2不应该闪烁的才对?请问问题出在哪里。
