Note: ICBRH/ICBRL settings in these tables are calculated using the following values:
SCL0 line rising time (tr): 100 kbps or less (Sm): 1000 ns, 400 kbps or less (Fm): 300 ns
SCL0 line falling time (tf): 400 kbps or less (Sm/Fm): 300 ns
For the specified values of SCL0 line rising time (tr) and SCL0 line falling time (tf), see the I
Semiconductors.
