    Prescaler, Timer 1, Timer 2 and Timer 3 count start timing and
    count time when operation starts
    Count starts from the first rising edge of the count source (2) af-
    ter Prescaler, Timer 1, Timer 2 and Timer 3 operations start (1).
    Time to first underflow (3) is shorter (for up to 1 period of the
    count source) than time among next underflow (4) by the timing
    to start the timer and count source operations after count starts.
    Fig. 29 Timer count start timing and count time when opera-
    tion starts (Prescaler, Timer 1, Timer 2 and Timer 3)
    Timer 4 count start timing and count time when operation starts
    Count starts from the rising edge (2) after the first falling edge of
    the count source, after Timer 4 operations start (1).
    Time to first underflow (3) is different from time among next un-
    derflow (4) by the timing to start the timer and count source
    operations after count starts.
