Notes:
1. Units for these specifications are in SDRAM_CLK units.
2. The actual values depend on the setting of the digital filter frequency sampling rate (DFFSR) bits in the frequency
divider register I2CFDR. Therefore, the noted timings in this table are all relative to qualified signals. The qualified
SCL and SDA are delayed signals from what is seen in real time on the I2C bus. The qualified SCL, SDA signals
are delayed by the SDRAM_CLK clock times DFFSR times two plus one SDRAM_CLK clock. The resulting delay
value is added to the value in the table (where this note is referenced). See Figure 17.
3. Timing is relative to the sampling clock (not SCL).
4. FDR[x] refers to the frequency divider register I2CFDR bit x.
5. Input clock low and high periods in combination with the FDR value in the frequency divider register (I2CFDR)
determine the maximum I2C input frequency. See Table 13.
