In cases where the rise time of the 9th clock of SCL exceeds the stipulated value because of a
large bus load capacity or where a slave device in which a wait can be inserted by driving the
SCL pin low is used, the stop condition instruction should be issued after reading SCL after the
rise of the 9th clock pulse and determining that it is low.
