EV1: EVF=1, ADSL=1, cleared by reading SR1 register.
EV2: EVF=1, BTF=1, cleared by reading SR1 register followed by reading DR register or when DMA
EV3: EVF=1, BTF=1, cleared by reading SR1 register followed by writing DR register or when DMA
EV3-1: EVF=1, AF=1, BTF=1; AF is cleared by reading SR1 register, BTF is cleared by releasing the
lines (STOP=1, STOP=0) or writing DR register (for example DR=FFh). Note: If lines are released by
STOP=1, STOP=0 the subsequent EV4 is not seen.
EV4: EVF=1, STOPF=1, cleared by reading SR2 register.
