The data format is MSB justified.
Set by control resistor SEL_EEST.
SEL_EEST bit= “0”: EEST pin
SEL_EEST bit= “1”: RSTO_N Monitor internal reset process.
Compatible with MSB / LSB justified 24, 20 and 16 bits.
Compatible with MSB / LSB justified 24, 20 and 16 bits.
Compatible with MSB / LSB justified 24, 20 and 16 bits. Normally connected
to Bluetooth line (sending).
Normally goes “L” by control register setting.
Normally goes “L” by control register setting.
When a crystal oscillator is used, connect it between XTI and XTO.
When an external clock is used, leave this pin open.
Connect a crystal oscillator between this pin and the XTO pin, or input an
external CMOS clock to the XTI pin.
Connect to AVSS.
EESEL pin = “L” : Normal mode
EESEL pin = “H”: In self-boot up mode using an AKM EEPROM, AK6514C
I2CSEL pin = “L”: Normal serial interface
I2CSEL pin = “H”: I2CBus selected mode. SCL and SDA are active.
I2CSEL should be connected to “L” (DVSS) or “H” (DVDD).
Connect to DVSS.
Master Mode: Outputs 64fs or 32fs clock.
Slave Mode: Outputs BITCLK_I clock.
Master Mode: Outputs 64fs or 32fs clock.
Slave Mode: Outputs SYNC_I clock.
RSTO_N pin =“L”: Reset mode, RSTO_N pin =“H”: Exit reset mode.
