来自源或sfr的无法访问的寄存器

你好伊万，
 
 
您已通过关联的PCTL启用了一些IP（参见RM）
（比较内存映射以获得相关的数字）

Hello Ivan ,


you have enable some IPs by associated PCTL (cf in RM)
(cf memory map to have the associated number)

• /* clock gating if present.*/
  

• SPCSetPeripheralClockMode(?????,
  

•                           
  

• SPC5_ME_PCTL_RUN(2) | SPC5_ME_PCTL_LP(2));

你好，Erwan，
 
 
感谢您的建议。
 
我尝试了你的解决方案，但它没有成功。我无法理解你建议在哪里找到。如果我在项目中复制了函数名（我用向导生成了板代码），我找不到该函数。
 
遵循建议一直很有帮助。我发现了ME模块以及必须激活外围设备的事实。据我所知，我发现在RUN模式下，设备的外设已停用。
 
我用过这段代码：
 
 
它的工作原理。
 
你对这段代码有什么建议吗？我不知道为什么我不能应用你的解决方案？可能我误解了它。
 
谢谢，
 伊万

Hello Erwan,


thanks for the advice.  

I tried your solution, but it didn't work out. I cannot understand where to find that you suggested. If I copy the function name in my project (where I generated the board code with the wizard), I cannot find the function.

Following the advice has been helpful. I discovered the ME module and the fact that peripherals must be activated. I found that the device, in RUN mode, had the peripherals deactivated, as you told.

I used this code:

• /* Activate extern peripherals. */
  

• UBYTE ME_MASK = 0b11111111;
  

• ME.RUN_PC0.R = ME.RUN_PC0.R | ME_MASK;
  

and it works.

Do you have any suggestions regarding this piece of code? Any idea on why I cannot apply your solution? Probably I misinterpreted it.

Thank you,
Ivan

我在这里发帖补充说，我发现的解决方案有一个奇怪的问题。
 
 
如果我使用调试器逐步运行代码，在我发布的代码之后，我可以使用ADC0寄存器。
 
但在运行模式下，激活码后，寄存器仍保留在?????状态和我进入异常。
 
似乎我错过了一些重要的东西。
 
有人有想法吗？
 
谢谢，
 伊万
 
编辑：
我明白问题在哪里。我错过了这两行（抱歉有点符号）：
 
 ME.MCTL.R = 0b01000000000000000101101011110000;
 ME.MCTL.R = 0b01000000000000001010010100001111;
 
这样，我控制转换到RUN0状态并加载配置（因此ADC转换器被激活）。首先写：模式选择+键。第二次写：模式选择+反转键。有关模式控制寄存器（ME_MCTL），请参见RM。
 
我在调试时没有出现问题，因为在断点处停止执行，命令自动从DRUN转换到RUN0模式加载配置。
但是，如果我没有停止应用程序，系统的状态仍然在DRUN中，因此我的配置未加载。
 
问候，
 伊万



以下为原文





I post here to add that the solution that I found have a strange problem.


If I run the code step by step using the debugger, after the code that I posted I can use the ADC0 register.

But in run mode, after the activation code, the register remains in ????? status and I go in exception.

It seems that I miss something important.

Someone have ideas?

Thanks,
Ivan

Edit:
I understood where the problem was. I missed this two lines (sorry for the bit notation):

ME.MCTL.R = 0b01000000000000000101101011110000;
ME.MCTL.R = 0b01000000000000001010010100001111;

With this, I control a transition to the RUN0 state and configuration is loaded (so ADC converter is activated). First write: mode selection + key. Second write: mode selection + inverted key. See RM for Mode Control Register (ME_MCTL).

The problem didn't arise when I was debugging, beacuse stopping the execution on a break point commanded automaticcaly a transition from DRUN to RUN0 mode loading the config.
But if I didn't stop the application, the status of the system remained in DRUN and so my configuration were not loaded.

Regards,
Ivan

你好伊万，
 
 
很好，你找到你的问题..
不容易找到，但往往解决方案是在RM ;-)
