PERIPHERAL DEVICE INPUT/OUTPUT TIMING
(VCC = 5 V±0.5 V, VSS = 0 V, Ta = –20 to 85 °C, f(fsys) = 20 MHz unless otherwise noted)
∗ ^{For limits depending on f(fsys), their calculation formulas are shown below. Also, the values at f(fsys) = 20 MHz are shown in ( ).}

Note : The TAiIN input cycle time requires 4 or more cycles of a count source. The TAiIN input high-level pulse width and the TAiIN input low-level pulse width
respectively require 2 or more cycles of a count source. The limits in this table are applied when the count source = f2 at f(fsys) ≤ 20 MHz.
