Note 1: SCL clock Low width (output) = (2
Note 2: SCL clock High width (output) = (2
Note 3: The output data hold time is equal to 12x of internal SCL.
Note 4: The Philips I2C-bus specification states that a device must internally provide a hold time of at least 300 ns for

the SDA signal to bridge the undefined region of the falling edge of SCL. However, this SBI does not satisfy this
requirement. Also, the output buffer for SCL does not incorporate slope control of the falling edges; therefore,
the equipment manufacturer should design so that the input data hold time shown in the table is satisfied, in-
cluding tr/tf of the SCL and SDA lines.
SCL I/O pins must be floating so that they don't obstruct the bus lines. However, this SBI does not satisfy this requirement.
In the table below, the letter x represents the I2C operation clock cycle time which is identical to the fsys
n denotes the value of n programmed into the SCK (SCL output frequency select) field in the SBIxCR.
