WebbBefore starting an I2C transaction, the size data to be transfered is written into the new Alternative Command Register. For each byte transferred, the I2C controller decreases this counter and automatically sends a STOP condition when the counter value reaches 0, that is to say when the last byte of the transaction has been sent/received.
