32. Electrical Characteristics
Note 1. t
IICcyc
: RIIC internal reference count clock (IICφ) cycle
Note 2. 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 3. C
b
is the total capacitance of the bus lines.
