[AK4452]
■ Parallel Mode
Parallel mode is available by setting the I2C pin = “H”, and the PS pin = “H”. Audio interface format of the
parallel mode is controlled by TDM1-0 bits and DIF bit (Table 26). Daisy Chain mode is also available by
setting the DCHAIN pin = “H”. In parallel mode, the clock setting mode is always in auto setting mode
(ACKS mode is enabled and fixed internally).
Zero detection function is not available in parallel mode. All functions controlled exclusively by Serial mode
are only available in their default register settings.

■ Serial Control Interface
The AK4452’s functions are controlled through registers. The registers may be written by two types of control
modes. The internal registers are controlled in 3-wire serial control mode when the I2C pin = “L”, and in I²C
bus control mode when the I2C pin = “H” and the PS pin = “L”.
