5 / 9 page 5/9 MSM9842 ¡ Semiconductor FEDL9842-02 PIN DESCRIPTIONS Symbol Type Description 16-bit serial data output pin when external DAC is used. Synchronizing clock for 16-bit serial data input when external DAC is used. Digital power supply pin. Insert a minimum 0.1 mF bypass capacitor between this pin and DGND pin. DASD O SOCK O XT XT I O VCK O RESET I TEST0 TEST1 TEST2 I TEST4 O AOUTL O AOUTR O DVDD — Oscillator connection pins. When external clock is used, input clock into XT pin and leave XT pin open. Outputs sampling frequency selected at playback. This sampling frequency is used as a synchronizing signal when external DAC is used. When this pin is "L", the LSI is initialized. Pins for testing. Set the pins to "L". Pin for testing. Set the pin to "OPEN". Left side output pin for built-in LPF. This is the output pin of playback wavefroms, and is connected to the amplifier for driving speakers. Right side output pin for built-in LPF. This is the output pin of playback wavefroms, and is connected to the amplifier for driving speakers. DGND — Digital GND pin. AVDD — Analog power supply pin. Insert a minimum 0.1 mF bypass capacitor between this pin and AGND pin. AGND — Analog GND pin. IOW I Signal to write external memory data to MSM9842 during DMA transfer. If DMA transfer is not used, set this pin to "H" level. TEST3 I Pin for testing. Set the pin to "H". |
