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.
EV3: EVF=1, BTF=1, cleared by reading SR1 register followed by writing DR register.
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 by writing DR register (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.
EV5: EVF=1, SB=1, cleared by reading SR1 register followed by writing DR register.
EV6: EVF=1, cleared by reading SR1 register followed by writing CR register (for example PE=1).
EV7: EVF=1, BTF=1, cleared by reading SR1 register followed by reading DR register.
EV8: EVF=1, BTF=1, cleared by reading SR1 register followed by writing DR register.
EV9: EVF=1, ADD10=1, cleared by reading SR1 register followed by writing DR register.
