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 does not exceed the values given in the table in

shown in table 15.5. However, because of the rise and fall times, the I
specifications may not be satisfied at the maximum transfer rate. Table 15.7 shows output
timing calculations for different operating frequencies, including the worst-case influence of
rise and fall times. The values in the above table will vary depending on the settings of the
IICX bit and bits CKS0 to CKS2. Depending on the frequency it may not be possible to
achieve the maximum transfer rate; therefore, whether or not the I
specifications are met must be determined in accordance with the actual setting conditions.
