RSCI 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-speed interface high-drive output is selected by the drive capacity control register.
