无法选择RC5作为输出

HYALL，环境：Win 10 /MPLAB X V3.40/MCC V3.16/XC8设备：PIC18F26K22i已使用MCC配置MSSP1作为I2C主控器。引脚RC3和放大器RC4分别被指定为SCL&SDA。然而，在引脚管理器网格中，我无法选择RC5作为输出。一条消息弹出我们“无法取消在引脚管理器中的引脚RC5上选择SDO1。对于设置“sdopin”，有多种可选选项，因此自动分位数。无法进行操作。请在MSSP1模块的Easy Setupor Register视图中配置备选的“sdopin”值。“无法在EasySetup&Register视图中找到MSSP1模块中建议的备选分配。我缺少什么？”谢谢

    Hi all,

Environment: Win 10 / MPLAB X v3.40 / MCC v3.16 / XC8
Device: PIC18F66K22

I have used MCC to configure MSSP1 as I2C master. Pins RC3 & RC4 have been assigned as SCL & SDA respectively.

However, in the pin manager grid, I am unable to select RC5 as an output.

A message pops us
"Unable to deselect SDO1 on pin RC5 in the pin manager.
There are multiple, alternative options for the setting "sdopin",
so an automatic decision cannot be made.

Please configure an alternative "sdopin" value in the Easy Setup
or Register view of the MSSP1 module."

Unable to locate the alternative assignment as suggested in the MSSP1 module in both Easy setup & Register view.

What am I missing?

Thanks
