125 / 179 page  R01DS0343EJ0120 Rev.1.20 Page 125 of 179 Nov 15, 2023 RX72N Group 2. Electrical Characteristics 2.4.7.9 SCI Note 1. tPBcyc: PCLKB cycle; tPAcyc: PCLKA cycle Note 2. When the SEMR.ABCS and SEMR.BGDM bits are set to 1 Table 2.36 SCI Timing Conditions: VCC = AVCC0 = AVCC1 = VCC_USB = VBATT = 2.7 to 3.6 V, 2.7 V ≤ VREFH0 ≤ AVCC0, VSS = AVSS0 = AVSS1 = VREFL0 = VSS_USB = 0 V, PCLKA = 8 to 120 MHz, PCLKB = 8 to 60 MHz, Ta = Topr, Output load conditions: VOH = 0.5 × VCC, VOL = 0.5 × VCC, C = 30 pF, High-drive output is selected by the drive capacity control register.
