编程后将MCLR设置为三态?

我有一个使用MCLR作为输入的项目。用PICtiT2 MCLR放在编程后的三态,但是用皮卡4,似乎PIN保持高。这有什么设置吗?

    I have a project that uses MCLR as input. With Pickit2 MCLR is put to tristate after programming however with Pickit 4 it seems the pin is held HIGH. Is there a setting for this?

在编程后,您是否试图使用MCLR作为通用I/O?我不相信你能做到这一点。它致力于MCLR对所有我工作的设备,所以我不知道你可以如何使用它作为除MCLR以外的任何东西。

    Are you trying to use MCLR as general purpose I/O after programming? I don't believe that you can do that. It's dedicated to MCLR on all of the devices I've worked with, so I don't see how you could use it as anything other than MCLR.

在您没有使用它的设备上没有专用于MCLR。

On devices you haven't worked with it is not dedicated to MCLR.

我们发现,从RESET释放是不正确的皮卡4,我们正在进行一个修复工作,并希望将在四月发布的MPLAB X。

    We have found that release from reset is not working correctly with PICkit 4 we are working on a fix, and hopefully will be in the April release of MPLAB X.
