2. Electrical Characteristics

Note:

tIICcyc: RIICHS internal reference clock (IICφ) cycle

Note 1. The value within parentheses is applicable when the value of the ICICR.NF[3:0] bits is 0011b while the digital filter is enabled by

the setting ICICR.NFE = 1. Note that, in Hs-mode, the lower-order 2 bits of the NF[3:0] bits are ignored and the number of

stages in the digital filter is single.

Note 2. Cb is the total capacitance of the bus lines.
