PERIPHERAL DEVICE INPUT/OUTPUT TIMING (VCC = 5 V±10 %, VCC = 0 V, Ta = –20 to 85 °C, unless otherwise noted)
∗ ^{If the values depends on external clock frequency f(XIN), formulas of the limits are shown below. Also, the values at f(XIN) = 40 MHz in high-}
speed running and at f(XIN) = 25 MHz in low-speed running are shown in ( ). At this time, the clock source select bit is “0.” When the clock
source select bit is “1”, regard f(XIN) in tables as 2·f(XIN).
∗ ^{The rise and fall time of input signal must be 100 ns or less respectively, unless otherwise noted.}

Note : The TAiIN input cycle time requires 4 or more cycles of count source. The TAiIN input high-level pulse width and the TAiIN input low-level pulse width
respectively require 2 or more cycles of the count source. The limits in the table are the values when the count source is f(XIN)/4 in high-speed running
(f(XIN) ≤ 40 MHz) and when the count source is f(XIN)/2 in low-speed running (f(XIN) ≤ 25 MHz). At this time, the clock source select bit is “0.”
