5 / 10 page SM1124 Series NIPPON PRECISION CIRCUITS—5 Input during playback mode only Input during non-playback mode Playback control The ST pin controls the start of playback. While ST is HIGH (VDD), the tune is played repeatedly, and when ST goes LOW (VSS), playback stops. Tunes are selected by the input serial data on pins SI and ST CLK ST CLK SC. The final 4 bits form the valid selection data, and this data is retained even after playback. If serial data is input during playback, the SM1124 ignores this data and playback continues. * Pin SC should be LOW when either a LOW-to-HIGH or HIGH-to-LOW transition occurs on pin ST. ,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,, SI SC ST MTO B3 B2 B1 B0 Invalid Data Valid Data Invalid Data Serial data selection1 B 3 B 2 B 1 B 0 S T Music selection LLLL L → H 1st tune LLL H L → H 2nd tune LL H L L → H 3rd tune LL H H L → H 4th tune LH L L L → H 5th tune LH LH L → H 6th tune LH H L L → H 7th tune L HHH L → H 8th tune 1.
