BQ40Z50-r3 GPIO LEDCNTLC(Pin22)无法设置



BQ40Z50-R3

设置如下寄存器:

使能GPIO_EN,关闭LED_EN。

Settings-Configuration:

Flag Map Set Up 设置为 0x8434可以在Charging Status在HV状态下将GPIO LEDCNTLA(Pin20引脚)拉高。

Flag Map Set Up 设置为 0x8234可以在Charging Status在HV状态下将GPIO LEDCNTLB(Pin21引脚)拉高。

Flag Map Set Up 设置为0x8634却无法拉高GPIO LEDCNTLC(Pin22引脚),使用GPIO Write() 写入0x0040方式也无法拉高。

请问我该如何做才能控制GPIO LEDCNTLC(Pin22引脚)?
