As per the Philips IIC bus specification, the IIC Master can have 0 ns data hold time on SDA. However, the IIC slave requires 300 ns data hold time on SDA; this can be achieved by configuring the parameter C_SCL_INERTIAL_DELAY by the required hold time. The data sheet is updated for the use of these parameters in slave and master mode.
For example:
If the PLB bus clock frequency is 100 MHz (10 ns) to have 300 ns data hold time on SDA, the parameter S_SCL_INERTIAL_DELAY needs to be configured for the integer value 30.
Parameter C_SDA_INERTIAL_DELAY needs to be configured for value 0.
