DESCRIPTION

45

TBCK/GPIO1 Digital Input/Output Modulation 64fs bit clock input. General-purpose I/O input/output pin.

46

TLRCK/GPIO2 Digital Input/Output Modulation fs clock input. General-purpose I/O input/output pin.

47

TDATA/GPIO3 Digital Input/Output Modulation serial audio data input. General-purpose I/O input/output pin.

48

TXO/GPIOEN Digital Output/Input Modulation data output. General-purpose I/O enable input pin.

Notes:

1. Input/output I or O = −0.3 to 3.6V, except annotated pins: −0.3 to +5.5V

2. Pins 32 and 33 are latch address setting input pins when pin 41 = Low.

3. Pin 34 is the demodulation function master or slave setting input pin when pin 41 = Low.

4. Pin 35 is the modulation function or general-purpose I/O function switch setting input pin when pin 41 = Low.

5. Perform ON/OFF for all power supplies with the same timing as a latch-up countermeasure.
