is necessary: (a) secure a start/stop condition issuance interval; (b) adjust the rise and
fall times by means of a pull-up resistor and capacitive load; (c) reduce the transfer rate;
(d) select slave devices whose input timing permits this output timing.
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
met must be determined in accordance with the actual setting conditions.
