Hello @tianxb,

I have tried disconnecting several debuggers in the JTAG mode using the available debugging interfaces, but I could not clear the bit with the external pin reset (reset_b).

What is the background here? Why do you need to clear the bit?

The POR clears it in both SWD and JTAG.

 

Thanks,

Daniel

 To avoid EDB being cleared by mistake ,I'm just curious why the document has this sentence, I also have tried disconnecting several debuggers in the JTAG mode using the available debugging interfaces, but I could not clear the bit with the external pin reset (reset_b).

 Maybe it's useless
