SDA

Internal clock
BBSY bit
Note that the clock may not be output properly during the next master send if receive data
(ICDR data) is read during the time between when the instruction to issue a stop condition is
executed (writing 0 to BBSY and SCP in ISSR) and when the stop condition is actually
generated.
In addition, overwriting of IIC control bits in order to change the send or receive operation
mode or to change settings, such as for example clearing the MST bit after completion of
master send or receive, should always be performed during the period indicated as (a) in Figure
13.21 below (after confirming that the BBSY bit in the ICCR register has been cleared to 0).
