Note 7. This value is the time from the rising edge of LRCK after data is input to rising edge of LRCK after data is output,
when LRCK for Output data corresponds with LRCK for Input.

Note 8. Typ and max values are the value of AVDD+DVDD in each power supply voltage.
Power supply current of each path@Slave Mode, AVDD=DVDD=3.3V, FSI=FSO=48kHz
1. PORT1 → SRC → PORT3: AVDD=5mA(typ), DVDD=10mA(typ)
2. PORT2 → SRC → PORT3: AVDD=5mA(typ), DVDD=10mA(typ)
3. DIR → SRC → PORT3: AVDD=6mA(typ), DVDD=9mA(typ)
Note 9. All digital input pins are held DVSS.
