What is status of GPIO13 after reset?

Postby YxWang » Thu Dec 13, 2018 6:00 am

There,

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?

Hi there,

The IO_MUX table has been updated since V2.7. So there should not be wpu. Please find the latest datasheet at: https://www.espressif.com/sites/default ... eet_en.pdf. Thanks.
