extended. SCL rise time is determined by the pull-up resistance and load capacitance of the
SCL line. To insure proper operation at the set transfer rate, adjust the pull-up resistance and
load capacitance so that the SCL rise time falls below the values given in the table below.
When issuing a retransmission start condition, the condition must be issued after the SCL clock
falls during the acknowledge bit reception period. After the end of the acknowledge bit, the
next data should be written to ICDR after SCL goes high. Figure 13.16 shows the
recommended program flow for issuing a retransmission start condition. A timing chart for the
flowchart in figure 13.16 is shown in figure 13.17.
