I2C TIMING SPECIFICATIONS
Guaranteed by initial characterization. All values were measured with the input filtering enabled. CB refers to the capacitive load on the bus line,
with tr and tf measured between 0.3 VDD and 0.7 VDD (see Figure 2). Unless otherwise noted, VDD = 2.7 V to 5.5 V and TA = TMIN to TMAX.
