[AK4458]
■ 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 30). Daisy Chain mode is also available by
setting the DCHAIN pin = “H” (Table 15). In parallel mode, the audio interface format is always in auto
setting mode and reset is released.
Zero detection function and functions set by registers are not available in parallel mode.

■ Serial Control Interface
The AK4458’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”.
