The values in the above table will vary depending on the settings of the IICX bit and bits CKS2 to
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.
