CLEAR PRESET

001aag411

(1) Clear overrides load, data and count inputs.

(2) When counting up, the count down clock input (CPD) must be HIGH, when counting down the count up clock input

(CPU) must be HIGH.

Sequence

Clear (reset outputs to zero);

load (preset) to binary thirteen;

count up to fourteen, ﬁfteen, terminal count up, zero, one and two;

count down to one, zero, terminal count down, ﬁfteen, fourteen and thirteen.
