软件复位后保持引脚状态为高电平

引脚在复位后的高Z，直到配置完成。因此，当使用外部上拉电阻（5K）将保持引脚高。

  The pins are in high-z after reset until the configuration is done. So when using an external pull up resistor (5K) will keep the pin high.

我已经实现了类似的功能，使用其他微控制器，他们确实保持他们的引脚状态后，软件重置，所以我认为这也是可能的PSoC而不使用外部电阻器。



     以下为原文
  I have implemented similar functionality using other microcontrollers and they do keep their pin state after a software reset, so I thought it was also possible with psoc without using an external resistor.

请让我问一个问题。
我知道，电源控制引脚是由过程驱动，成为过程中的复位序列HI-Z。
那么，电源控制信号是如何在开机时播放的呢？谁能供电？
如果将该控制信号重新定义为被拉到VDD的低活动信号以禁用电源，则最好理解该系统。
当做，

  Please let me ask a question.
I understand that a power supply control pin is driven by the PRoC BLE which becomes Hi-Z during the PRoC BLE's reset sequence.
Then, how do this power supply control signal play during power-on?  Who does enable the power supply?
 
If this control signal is re-defined as a LOW-ACTIVE signal pulled up to VDD to disable the power supply, it is better to understand the system.

电源使能由2个输入控制，即来自PROC和A按钮的信号，该信号连接到电池。
最初，为了打开系统，按钮被按下，这使得电源和第一动作的PRC模块所做的是设置其信号高，以保持电源启用。一旦用户释放按钮，电源就因为模块的信号而保持开启。
该按钮还连接到PROC模块的输入，用于用户操作。例如，为了关闭模块，按钮被按下一定的时间，并且PROC模块将信号设置为低。用户释放按钮后，电源关闭。
输入Bootloader，我将一个值写入BLE特性，程序设置它要进入引导加载程序并重置软件。我前面提到的问题是，信号切换到高阻抗状态，并且不可能将上拉电阻与当前PCB设计连接起来。
我想知道的是，是否有一种方法跳转到引导加载程序，使输出保持很高。



     以下为原文
  The power supply enable is controlled by 2 inputs the signal from the proc and a button, that is connected to a battery.
 
Initially, to turn on the system, the button is pressed this enables the power supply and the first action the proc module does is set its signal high to keep the power supply enabled. Once the user releases the button the power supply remains on because of the signal from the module.
 
The button is also connected to an input of the proc module, for user actions. For example to turn off the module the button is pressed for a certain amount of time and the proc module sets the signal low. After the user releases the button the power supply is turned off.
 
To enter the bootloader, I write a value to a ble characteristic and the program sets that it wants to enter the bootloader and does the software reset. The problem I have, as mentioned before, is that the signal switches to the high impedance state, and it's not possible to connect a pullup resistor with the current pcb design.
 
What I would like to know is if there is a way to jump to the bootloader so that the output remains high.

Bootloader组件在其数据表下具有BootloadSeriStad（）函数。我会从那里开始。（它确实提到，在成功加载一个新的引导加载映像之后，它会重置该单元）。

  The Bootloader component has the Bootloader_Start() function under its datasheet. I would start there. (It does mention that it resets the unit upon successful loading of a new bootload image however).
