Description
Multipurpose GPIO or Serial Output Port Data 1 (SDATA_OUT1). See the Multipurpose Pins
section for more details.
Multipurpose GPIO, Serial Output Port Data 0, or TDM Data Output (SDATA_OUT0). See the
Multipurpose Pins section for more details.
Multipurpose GPIO or Serial Output Port LRCLK (OUTPUT_LRCLK). See the Multipurpose
Pins section for more details.
Drive for 1.8 V Regulator. The base of the voltage regulator external PNP transistor is driven
from VDRIVE. See the Voltage Regulator section for details.
Supply for Input and Output Pins. The voltage on this pin sets the highest input voltage
that should be seen on the digital input pins. This pin is also the supply for the digital
output signals on the control port and MP pins. Always set IOVDD to 3.3 V. The current draw
of this pin is variable because it is dependent on the loads of the digital outputs.
Multipurpose GPIO or Serial Output Port BCLK (OUTPUT_BCLK). See the Multipurpose Pins
section for more details.

follows:
ADDR1: I
four ADAU1701 devices can be used on the same I
details.
CDATA: SPI Data Input. See the SPI Port section for details.
WB: EEPROM Writeback Trigger. A rising (default) or falling (if set in the EEPROM messages)
edge on this pin triggers a writeback of the interface registers to the external EEPROM. This
function can be used to save parameter data on power-down. See the Self-Boot section for
details.
SPI Latch Signal/Self-Boot EEPROM Write Protect. This is a multifunction pin as follows:
CLATCH: SPI Latch Signal. Must go low at the beginning of an SPI transaction and high at the
end of a transaction. Each SPI transaction can take a different number of cycles on the CCLK
pin to complete, depending on the address and read/write bit that are sent at the beginning
of the SPI transaction. See the SPI Port section for details.
WP: Self-Boot EEPROM Write Protect. This pin is an open-collector output when in self-boot
mode. The ADAU1701 pulls this low to enable writes to an external EEPROM. This pin
should be pulled high to 3.3 V. See the Self-Boot section for details.

SDA: I
should have a 2.2 kΩ pull-up resistor. See the I
COUT: This SPI data output is used for reading back registers and memory locations. It is
three-stated when an SPI read is not active. See the SPI Port section for details.

SCL: I
boot mode, this pin is an open-collector output (I
should have a 2.2 kΩ pull-up resistor. See the I
CCLK: SPI Clock. This pin can either run continuously or be gated off between SPI
transactions. See the SPI Port section for details.
Multipurpose GPIO, Serial Output Port Data 3 (SDATA_OUT3), or Auxiliary ADC Input 0. See
the Multipurpose Pins section for more details.
Multipurpose GPIO, Serial Output Port Data 2 (SDATA_OUT2), or Auxiliary ADC Input 3. See
the Multipurpose Pins section for more details.
Multipurpose GPIO, Serial Input Port Data 3 (SDATA_IN3), or Auxiliary ADC Input 2. See the
Multipurpose Pins section for more details.
Multipurpose GPIO, Serial Input Port Data 2 (SDATA_IN2), or Auxiliary ADC Input 1. See the
Multipurpose Pins section for more details.
Reserved. Tie to ground, either directly or through a pull-down resistor.
Crystal Oscillator Circuit Output. Connect a 100 Ω damping resistor between this pin and
the crystal. Do not use this output to directly drive a clock to another IC. If the crystal
oscillator is not used, this pin can be left disconnected. See the Using the Oscillator section
for details.
Master Clock Input. MCLKI can either be connected to a 3.3 V clock signal or be the input
from the crystal oscillator circuit. See the Setting Master Clock/PLL Mode section for details.
