I2C Input/Output Timing Specifications
Table 16 lists specifications for the I2C input timing parameters shown in Figure 18.
Table 17 lists specifications for the I2C output timing parameters shown in Figure 18.
Figure 18 shows timing for the values in Table 16 and Table 17.

Note: Output numbers depend on the value programmed into the IFDR; an IFDR programmed with
the maximum frequency (IFDR = 0x20) results in minimum output timings as shown in Table 17. The
I2C interface is designed to scale the actual data transition time to move it to the middle of the
I2C_SCL low period. The actual position is affected by the prescale and division values programmed
into the IFDR; however, the numbers given in Table 17 are minimum values.

Because I2C_SCL and I2C_SDA are open-collector-type outputs, which the processor can only
actively drive low, the time I2C_SCL or I2C_SDA take to reach a high level depends on external
signal capacitance and pull-up resistor values.
