Sorry everyone, I don't know Baidu‘s pictures can't be viewed. So I reposted a post.
On page 50 of ESP32_TRM_rev3.8.pdf, the table 18: IO_MUX Pad Summary. It write
.MTCK/ GPIO13 is IE = 1(input enabled) on after reset
But On page 58 of ESP32_DS_rev2.5.pdf, the IO_MUX list. It write
MTCK/ GPIO13 is wpu & ie = 1(pullup resistor, input enabled) on after reset.
So what is the state after GPIO13 reset?
