9. Initial System Settings
9.1 System Reset (XMODE)
The system operates correctly when XMODE is set to "H" after 3.0V or higher supply voltage is applied.
When XMODE is set to "L" after power is turned on, the system is reset.
To set chip address, master/slave, or pins 44 to 47 I/O, 10kΩ pull-down or pull-up resistors must be connected to
MOUT, AUDIO , CKST, and INT .
If none of MOUT, AUDIO , CKST, and INT are pulled down or pulled up, their pin state will get unstable when the
settings are entered, resulting in wrong setting. Pull-up or pull-down resistors must be connected to these pins without
fail.
