Product specification
Programmable multi-tone telephone ringer
PCD3360
7.6
Selection of tone sequences (TS1 and TS2)
TS1 and TS2 are effective when both FDE and FDI are HIGH, and V
DD
> V
stb
. TS1 and TS2 normally select one of the
four standard tone sequences shown in Fig.4. Different tone sequences of 15 or 16 consecutive tones and pauses can
be mask programmed to order. The seven tones (plus pause) available are shown in Fig.5, together with the
corresponding ROM codes.
The tone sequences are repeated continuously provided the enable conditions at inputs FDE and FDI are valid and
V
DD
> V
stb
. The first sequence and subsequent repetitions always begin with the first note in the sequence.
