OPERATIONAL INPUTS

Set minutes/reset seconds, switch S2

Operational inputs S1, S2 and S3 have an internal pull-up

resistor to facilitate use of external single-pole,

single-throw switches. A specific debounce circuit is

integrated as protection against contact debounce and

parasitic voltages.

When S2 is closed, the minute setting is corrected

according to the correction mode determined by S6 (see

Chapter “Input options”).

The seconds counter is reset to zero each time S2 is

closed, and begins running each time S2 is opened.

In the description below, an arrangement as shown in

Fig.5 is assumed and S1, S2 and S3 refer to the external

switches rather than the corresponding inputs.

Segment test/reset, switches S1 and S2

If S1 and S2 are closed simultaneously all LCD segments

are switched on. When the switches are released, the

clock starts at 1 : 00 in the 12-hour mode or 0 : 00 in the

24-hour mode.

Set hours, switch S1

Closure of S1 increments the hours according to the

correction mode selected by S6 (see Chapter

“Input options”).
