Function name
__STATIC_INLINE void LL_I2C_EnableIT_EVT (I2C_TypeDef *
I2Cx)
Function description

Notes
Any of these events will generate interrupt : Start Bit (SB)
Address sent, Address matched (ADDR) 10-bit header sent
(ADD10) Stop detection (STOPF) Byte transfer finished (BTF)
Any of these events will generate interrupt if Buffer interrupts
are enabled too(using unitary function
LL_I2C_EnableIT_BUF()) : Receive buffer not empty (RXNE)
Transmit buffer empty (TXE)
