I2C endianness - can we use HW Datashifter?

Postby ghost07 » Fri Dec 15, 2023 1:59 pm

Hello, from the ESP32 Technical Reference Manual I can see I2C peripheral provides Data shifter module:

https://www.espressif.com/sites/default ... en.pdf#i2c
Page 285 / Figure 111. I2C Master Architecture
Page 297 / Register 11.2. I2C_CTR_REG (0x0004) / I2C_RX_LSB_FIRST

Is it possible to configure I2C driver or better - a transaction, to use this feature in ESP-IDF v4.4?
