* : Microcontroller register output or clock switching transition period signal.
** : 128fs, 256fs, 384fs, 512fs, or oscillator amplifier outputs.
*** : Other than I²S mode ; Low: right channel, High: left channel.
I²S mode ; Low: left channel, High: right channel.
1) I/O voltage handling :
I or O pins : –0.3 to +3.6V,
I5 pins : –0.3 to +5.5V
2) To prevent logic circuit latch-up, all power supply must be applied or removed simultaneously.
