Signal to write external memory data to MSM9842 during DMA transfer.
If DMA transfer is not used, set this pin to "H" level.
16-bit serial data output pin when external DAC is used.
Synchronizing clock for 16-bit serial data input when external DAC is used.
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 "H".
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.
Digital power supply pin. Insert a minimum 0.1 mF bypass capacitor between this pin and
DGND pin.
Digital GND pin.
Analog power supply pin. Insert a minimum 0.1 mF bypass capacitor between this pin and
AGND pin.
Analog GND pin.
