you can use IO command to check the IOMUX to judge whether it is reused or not. It is explained in the section of Debugging Methods, but it will not be explained here. If GPIO1_D0 and GPIO1_D1 are found to be reused as I2C1_SDA through IO command, the I2C...

像配置管脚作为通用输入输出口还是3个外设功能中的一个那样,来配置GPxMUXn或者AIOMUXn寄存器。默认的,所有GPIO的管脚在复位时都被配置为通用输入管脚。 Step 5. For digital general purpose I/O, select the direction of the pin:00 If the pin is configured as an GPIO, specify the direction of the pin...
