Digital Audio Serial Data Playback Input
Digital Audio Serial Data Record Output. The output voltage is referenced to DVDDIO.
Digital Audio Left-Right Clock Input/Output. LRCLK is the audio sample rate clock and
determines whether audio data is routed to the left or right channel. In TDM mode, LRCLK
is a frame sync pulse. LRCLK is an input when the device is in slave mode and an output
when in master mode.
Digital Audio Bit Clock Input/Output. BCLK is an input when the device is in slave mode
and an output when in master mode. The input/output voltage is referenced to DVDDIO.
Active-Low Hardware Interrupt Output. Connect a 10kΩ pullup resistor to V
Master Clock Input. Acceptable input frequency range is either 256 x f
60MHz.

Headphone Power Supply. Bypass to HPGND with a 1µF capacitor.
Charge-Pump Flying Capacitor Positive Terminal. Connect a 1µF ceramic capacitor
between C1N and C1P.
Charge-Pump Flying Capacitor Negative Terminal. Connect a 1µF ceramic capacitor
between C1N and C1P.
Speaker and Microphone Bias Power Supply. Bypass to SPK_GND with a 1µF capacitor.
Auxiliary Negative Differential Microphone Input or Single-Ended Line Input. AC-couple
with a series 1µF capacitor.
Auxiliary Positive Differential Microphone Input or Single-Ended Line Input. AC-couple
with a series 1µF capacitor.
