Note:
If a Bus Error occurs, a Stop or a repeated Start condition should be generated by the
Master to re-synchronize communication, get the transmission acknowledged and the bus
released for further communication

This bit is set by hardware when a general call address is detected on the bus while
ENGC=1. It is cleared by hardware detecting a Stop condition (STOPF=1) or when the
interface is disabled (PE=0).
0: No general call address detected on bus
1: general call address detected on bus
This bit is set and cleared by software. It is not cleared when the interface is disabled
(PE=0).
0: Standard I
1: Fast I
These bits select the speed of the bus (F
cleared when the interface is disabled (PE=0).
Refer to the Electrical Characteristics section for the table of values.
These bits contain the byte to be received or transmitted on the bus.

Transmitter mode: byte transmission start automatically when the software writes
in the DR register.
Receiver mode: the first data byte is received automatically in the DR register
using the least significant bit of the address. Then, the following data bytes are
received one by one after reading the DR register.
