5.9.6.6. SDA Hold Time
The I2C protocol specification requires 300 ns of hold time on the SDA signal in standard and fast speed modes. Board delays on the SCL and SDA signals can mean that the hold time requirement is met at the I2C master, but not at the I2C slave (or vice-versa). As each application encounters differing board delays, the I2C controller contains a software programmable register, IC_SDA_HOLD, to enable dynamic adjustment of the SDA hold time. IC_SDA_HOLD effects both slave-transmitter and master mode.
