4 / 16 page  1997 Apr 16 4 Philips Semiconductors Product specification 31/2-digit LCD car clock PCF1172C Fig.2 Segment designation of LCD. MSA989 B1 C1 A2 G2 D2 F2 E2 B2 C2 P1 (P3) P2 (P4) A3 G3 D3 F3 E3 B3 C3 A4 G4 D4 F4 E4 B4 C4 AM PM Fig.3 Display mode (12-hour with AM/PM annunciator). TIME MSA990 AM OPERATIONAL INPUTS 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. 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. Set hours, switch S1 Closure of S1 increments the hours according to the correction mode selected by S6 (see Chapter “Input options”). Set minutes/reset seconds, switch S2 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. 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. |
