Notes on I
C Bus Interface Stop Condition Instruction Issuance
If the rise time of the 9th SCL clock exceeds the specification because the bus load capacitance
is large, or if there is a slave device of the type that drives SCL low to effect a wait, after rising
of the 9th SCL clock, issue the stop condition instruction after reading SCL and determining it
to be low, as shown below.
