Case b : latched (dashed line); the timing below 0.4V is
450μs which is larger than 210μs. No latch reset as the
rise time from 0.4V to 1V is 300μs which is less than the
450μs.
Case c : latched and reset (dotted line); the timing
below 0.4V is 710μs which is larger than 210μs. But the
rise time from 0.4V to 1V is 560μs which is larger than
the latch reset blanking time of 450μs.
