5. Electrical Characteristics
Table 5.20 Timing of On-Chip Peripheral Modules (5)
Conditions: VCC = AVCC0 = VREFH = VCC_USB = 2.7 to 3.6 V, VREFH0 = 2.7 V to AVCC0
VSS = AVSS0 = VREFL/VREFL0 = VSS_USB = 0 V
PCLK = 8 to 50 MHz
T_a = T_opr
High drive output is selected by the drive capacity control register.

Note: t_IICcyc: RIIC internal reference clock (IIC) Cycle, t_Pcyc: PCLK cycle
Note 1. The value in parentheses is used when ICMR3.NF[1:0] are set to 11b while a digital filter is enabled with ICFER.NFE = 1.
Note 2. Cb indicates the total capacity of the bus line.
