不能控制PMA的一部分的引脚

嗨，我在我的自定义板与PIC32 MX27 0F256D和配置使用PMP通过MHC。我已经配置了8位数据-不需要地址复用-数据只出现在PMP总线-连同RD+WR信号。我需要使用PMA的一部分，因为PMA不能启用，所以我应该能够独立使用这些引脚。但我发现这是非常令人沮丧的，我不能控制PMA的一部分的引脚：（我写简单的HI /低信号上的一个端口引脚，它没有显示任何东西。我还尝试使用PMA的其他引脚，但看到相同的结果。在代码中，如果我注释了DVVPMP00IMALIZIZE（）行，那么我可以在那些PMA共享引脚上得到预期的输出。看来MHC没有为PMCON寄存器生成所需的ADRMUX位。我不知道如何跟踪实际写入的值。有人观察到类似的情况吗？有谁能帮助我知道我错过了什么？会真正感谢任何指针

    Hi,

I am working on my custom board with PIC32MX270F256D and configuring using PMP through MHC. I have configured for 8bit data - and don't need Address multiplexing - data only appear on PMP bus - along with RD + WR signals. I need to use the pins which are part of PMA bus, since PMA is not enabled I should be able to use these pins independently.

But I found this very frustrating that I am not able to control pins that are part of PMA :( I am writing simply hi/low signal on one of the port pin, and it does not show anything. I also tried using other pin of the PMA but seeing the same result. When in the code, if I comment out DRV_PMP0_Initialize() line, then I can get expected output on those PMA shared pins. It seems like MHC is not generating required ADRMUX bits for PMCON register. I am not sure how can I track to the actual values that are written.

Has anyone observed anything similar? Can anyone help me on what I am missing? would really apreciate any pointer

Thanks
Silas
