When arbitration is lost during transmitting the second frame or subsequent frame, take
avoidance measures.
Though it is prohibited in the normal I
bit is erroneously set to 1 and a transition to master mode is occurred during data transmission
or reception in slave mode. In multi-master mode, pay attention to the setting of the MST bit
when a bus conflict may occur. In this case, the MST bit in the ICCR register should be set to 1
according to the order below.
(a) Make sure that the BBSY flag in the ICCR register is 0 and the bus is free before setting
(b) Set the MST bit to 1.
(c) To confirm that the bus was not entered to the busy state while the MST bit is being set,
If ICDR is read in transmit mode (TRS = 1) or ICDR is written to in receive mode (TRS = 0),
the SCL pin may not be held low in some cases after transmit/receive operation has been
completed, thus inconveniently allowing clock pulses to be output on the SCL bus line before
ICDR is accessed correctly. To access ICDR correctly, read ICDR after setting receive mode
or write to ICDR after setting transmit mode.
In the I
mode (TRS = 1) and then the address is received in slave mode without performing appropriate
processing, interrupt handling may start at the rising edge of the 9th clock pulse even when the
