Hi folks,

The I2C_END_DETECT_INT_RAW interrupt request source bit is mentioned in chapter 11.3.7 of the ESP32 Technical Reference Manual v.3.4, but does not appear in the I2C_INT_RAW_REG register description in chapter 11.5. According to the SDK esp32/include/soc/i2c_reg.h line 331 and strangely missing bit field in the register description, bit number 4 seems to be the correct position.

In addition, the bit 4 description is also missing in the registers I2C_INT_CLR_REG, I2C_INT_ENA_REG and I2C_INT_STATUS_REG.

Q1: Can somebody confirm this?
Q2: Is this the right place to post device documentation errors?

Thanks in advance

Yes, we are aware of this, a fix will be in a future revision of the TRM. Thanks for the note, however, it's always appreciated to get feedback. If you see more errors in the TRM, feel free to post them here and we'll pass them to the documentation team.
