    20719 LHLGPIO

      请问:

             客户使用20719 I2C接口,发现除了映射到P25和P29管脚,通过super MUX映射到其他端口都无法使用。

             看资料介绍:

             LHL GPIOs are different from Arm GPIOs in few ways. LHL GPIOs can operate in low power modes and support mux-able peripherals, whereas Arm GPIOs can operate only in active mode with limited functionality. The functionalities that can be brought out to LHL I/Os are I2C, SPI, PUART, ACLK., and so on

          如果20719有16个GPIO支持LHL,为什么无法映射到其他端口,麻烦说明一下原因,谢谢!
