How to Release the SDA / SCL Lines
Set and subsequently clear the STOP bit when BTF is set. The SDA/SCL lines are released after
the transfer of the current byte.
Other Events
ADSL:
Detection of a Start condition after an acknowledge time-slot. The state machine is reset
and starts a new process. The ADSL bit is set and an interrupt is generated if the ITE bit is set. The
SCL line is stretched low.
STOPF:
Detection of a Stop condition after an acknowledge time-slot. The state machine is reset.
Then the STOPF flag is set and an interrupt is generated if the ITE bit is set.

Legend
:
S = Start, P = Stop, A = Acknowledge, NA = Non-acknowledge and EVx = Event (with interrupt if ITE
= 1)
EV1:
EVF = 1, ADSL = 1, cleared by reading register SR1.
EV2:
EVF = 1, BTF = 1, cleared by reading register SR1 followed by reading DR register.
EV3:
EVF = 1, BTF = 1, cleared by reading register SR1 followed by writing DR register.
EV3-1:
EVF = 1, AF = 1 and BTF = 1, AF is cleared by reading register SR2, BTF is cleared by
releasing the lines (write STOP = 1, STOP = 0 in register CR) or by writing to register DR (DR
= FFh).
Note:
If the lines are released by STOP = 1, STOP = 0, the subsequent EV4 is not seen.
EV4:
EVF = 1, STOPF = 1, cleared by reading register SR2.
