Function
9.6 MHz crystal connection. An external 9.6 MHz clock can also be used on
X1 (3.3V input). X2 cannot be used to drive external circuits.
PLL external RC network.
Reset input, active low. This is a Schmidt trigger input, allowing direct
connection of an RC network.
Power down, active low. When power down is active, then all Output pins will
be floated. The crystal oscillator will be stopped. To exit from power down,
PDWN should be high and RESET applied.
Test pins. Should be grounded.
General-purpose I/O pins. As inputs, can be used to configure the software.
P1 to P3 can also be used as three additional stereo serial inputs (six audio
channels).
When high, indicates that the synthesizer is up and running. May be used as
a RESET input for an external DAC.
