ESP32 Forum

Hi,

esp32-s2 has in its datasheet (page 42) specific pin state At Reset & After Reset. I would assume this is during the pin EN low and when EN is high.

esp32-c3 only has the pin state specified (page 17) for After Reset. Is there no difference between At/After Reset for this chip?

Hi John,
It takes some time to power up the chip. During power-up, the chip is at reset. Once the chip is powered up, the chip is released from reset, aka after reset.
At reset, only strapping pins are configurable, which is described in Chapter Chip Boot Control in Technical Reference Manual. Other pins cannot be configured at reset. That's the reason why we do not provide pin configurations at reset.
Hope this helps!
