I
The characterization timing is done using primetime considering an output load of 10 pF on
SCL and SDA. The operating conditions are V = 0.90 V, T
V =1. 10 V, T

The flip-flops used to capture the incoming signals are re-synchronized with the AHB clock:
so, no input delay calculation is required.
