Master (6 × (1 + TPR)) + 1 system clock cycles
Values depend on the value programmed into the TPR bit in the I2C Master Timer Period (I2CMTPR) register; a TPR programmed for the maximum I2CSCL frequency (TPR = 0x2) results in a minimum output timing listed in this table. The I2C interface is designed to scale the actual data transition time to move it to the middle of the I2CSCL low period. The actual position is affected by the value programmed into the TPR; however, the values in this table are minimum values.
Because I2CSCL and I2CSDA operate as open-drain-type signals, which the controller can only actively drive low, the time I2CSCL or I2CSDA takes to reach a high level depends on external signal capacitance and pullup resistor values.
