Conditions: VCC = AVCC0 = AVCC1 = VCC_USB = V_BATT = 2.7 to 3.6 V, 2.7 ≤ VREFH0 ≤ AVCC0,
VCC_USBA = AVCC_USBA = 3.0 to 3.6 V,
VSS = AVSS0 = AVSS1 = VREFL0 = VSS_USB = VSS1_USBA = VSS2_USBA = PVSS_USBA = AVSS_USBA = 0 V,
PCLKA = 8 to 120 MHz, PCLKB = 8 to 60 MHz, T_a = T_opr
High-drive output is selected by the driving ability control register.

t_IICcyc: RIIC internal reference clock (IIC) cycle, t_PBcyc: PCLKB cycle
The value within parentheses is applicable when the value of the ICMR3.NF[1:0] bits is 11b while the digital filter is enabled by
the setting ICFER.NFE = 1.
Cb is the total capacitance of the bus lines.
