Timer B input (Pulse period measurement mode)
Note: The TBiIN input cycle time requires 4 or more cycles of a count source. The TBiIN input high-level pulse width and the TBiIN 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.
