Note: • t_IICcyc: RIIC internal reference count clock (IICφ) cycle
Note 1. The value in parentheses is used when the ICMR3.NF[1:0] bits are set to 11b while a digital filter is enabled with the ICFER.NFE
bit = 1.
Note 2. C_b indicates the total capacity of the bus line.
Note 3. The minimum tsr and tsf specifications for fast mode are not set.
