KE 库函数中 GPIO_PinMaskType是指什么含义

请教，KE 库函数中 GPIO_PinMaskType是指什么含义？
是说当前Mask位不起作用嘛？

什么时候能对KE库出一个中文说明啊？

在库函数的哪里，有关于“GPIO_PinMaskType”的说明？

枚举类型变量，其定义了各个GPIO引脚的选择位，请找到gpio.h，查看该变量的定义。

mask 蒙板？
FEA能不能用一个例子说明它的具体作用、用处？

报告领导，查找结果如下：

别人阅读程序时能对使用哪个芯片引脚一目了然。

看你已经安装了[url=https://www.freescale.co
m/zh-Hans/webapp/sps/site/prod_summary.jsp?code=FRDM-KE06Z&fpsp=1&tab=Design_Tools_Tab#]KEXX_DRIVERS_V1.2.1_DEVD[/url] [img]https://www.freescale.co
m/files/graphic/SECURITYINFOIMAGE.gif[/img] : FRDM-KEXX Driver Library Package. 那么在安装路径下能够找到GPIO例子。
例如：E:\KEXX_DRIVERS_V1.2.1_DEVD\kexx_drv_lib\build\iar\ke06\GPIO_demo

在GPIO工程里就有其应用：
