17.3.4.1
Normal Processing
The timer increments at rising edges or decrements at falling edges on the TAjIN pin when input signals
to the TAjOUT (j = 2, 3) pin is high level.

Multiply-by-4 Processing
If the phase relationship is such that the input signal to the TAkIN pin goes high while the input signal to
the TAkOUT pin (k = 3, 4) is high, the timer increments at both rising and falling edges of the input
signal to pins TAkOUT and TAkIN. If the phase relationship is such that the input signal to the TAkIN pin
goes low while the input signal to the TAkOUT pin is high, the timer decrements at both rising and
falling edges of the input signal to pins TAkOUT and TAkIN.
