# Pin Description
1
64 DAC Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
63
2 DAC Serial Clock (Input/Output) - Serial clock for the DAC serial audio interface.
3
DAC Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on
the DAC serial audio data line.
4
51
Digital Power (Input) - Positive power supply for the digital section.
5
52 Digital Ground (Input) - Ground reference. Should be connected to digital ground.
6 Control Port Power (Input) - Determines the required signal level for the control port.
7
Serial Control Port Clock (Input) - Serial clock for the serial control port. Requires an external pull-up
resistor to the logic interface voltage in I²C mode as shown in the Typical Connection Diagram.
Serial Control Data (Input/Output) - SDA is a data I/O line in I²C mode and requires an external pull-up
8 resistor to the logic interface voltage, as shown in the Typical Connection Diagram. CDOUT is the output
data line for the control port interface in SPI mode.
9 Address Bit 1 (I²C)/Serial Control Data (SPI) (Input) - AD1 is a chip address pin in I²C mode; CDIN is
the input data line for the control port interface in SPI mode.
10 Address Bit 0 (I²C)/Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin in I²C mode; CS
is the chip select signal in SPI mode.
11
Interrupt (Output) - The CS42416 will generate an interrupt condition as per the Interrupt Mask register.
See “Interrupts” on page 37 for more details.
