S = Start, Sr = Repeated Start, P = Stop, A = Acknowledge, NA = Non-acknowledge, EVx = Event (with interrupt if ITE = 1)
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.
