Prescaler and Timer 1 count start timing and count time when op-
eration starts
Count starts from the first rising edge of the count source (2) af-
ter Prescaler and Timer 1 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.
When selecting CNTR input as the count source of Timer 1,
Timer 1 operates synchronizing with the falling edge of CNTR in-
put.
Fig. 24 Timer count start timing and count time when opera-
tion starts (Prescaler and Timer 1)
Timer 2 and Timer LC count start timing and count time when op-
eration starts
Count starts from the rising edge (2) after the first falling edge of
the count source, after Timer 2 and Timer LC 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.
