Register Control Interface
The AK4358 controls its functions via registers. 2 types of control mode write internal registers. In the I
2
C-bus mode, the
chip address is determined by the state of the CAD0 and CAD1 inputs. In 3-wire mode, the CAD1 input is fixed to “1” and
Chip Address C0 is determined by the state of the CAD0 pin. PDN = “L” initializes the registers to their default values.
Writing “0” to the RSTN bit resets the internal timing circuit, but the register data is not initialized.
* The AK4358 does not support the read command.
* When the AK4358 is in the power down mode (PDN = “L”) or the MCLK is not provided, Writing to control
register is invalid.

(1) 3-wire Serial Control Mode (I2C = “L”)
3-wire μP interface pins, CSN, CCLK and CDTI, write internal registers. The data on this interface consists of Chip
Address (2bits, C1/0; C1 is fixed to “1” and C0=CAD0), Read/Write (1bit; fixed to “1”, Write only), Register Address
(MSB first, 5bits) and Control Data (MSB first, 8bits). The AK4358 latches the data on the rising edge of CCLK, so data
should clocked in on the falling edge. The writing of data becomes valid by the rising edge of CSN. The clock speed of
CCLK is 5MHz (max).
