This bit is set by hardware when no acknowledge is returned. An interrupt is
generated if ITE=1. It is cleared by software reading SR2 register or by hardware
when the interface is disabled (PE=0).
0: No acknowledge failure

This bit is set by hardware when a Stop condition is detected on the bus after an
acknowledge (if ACK=1). An interrupt is generated if ITE=1. It is cleared by
software reading SR2 register or by hardware when the interface is disabled
(PE=0).
The SCL line is not held low while STOPF=1.
0: No Stop condition detected
1: Stop condition detected
