NOTES:
1
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 A-16. The I
2
C
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 A-16 are minimum values.
2
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.
