Remark 1. Calculate the rise time (tR) and fall time (tF) of the SDAAn and SCLAn signals separately, because
they differ depending on the pull-up resistance and wire load.
Remark 2. IICWLn: IICA low-level width setting register n
IICWHn: IICA high-level width setting register n
t
F: SDAAn and SCLAn signal falling times
tR: SDAAn and SCLAn signal rising times
f
MCK: IICA operating clock frequency
Remark 3. n = 0, 1
