Function Description
Remarks
O Bit clock output pin. 32fs, 48fs, or 64fs selectable by command. Normal speed:
3-5I/F
32fs = 1.4112 MHz
O L/R channel clock output pin. “L” for L channel and “H” for R
3-5I/F channel. Output polarity can be inverted by command.
Normal speed: 44.1 kHz
O Audio data output pin. MSB-first or LSB-first selectable by
3-5I/F command.
