Serial Control Interface
The AK4353 can control its functions via registers. Internal registers may be written by 2 types of control mode. The chip
address is determined by the state of the CAD0 and CAD1 inputs. PDN = “L” initializes the registers to their default
values. Writing “0” to the RSTN bit can initialize the internal timing circuit. But in this case, the register data is not be
initialized.
(1) 3-wire Serial Control Mode (I2C = “L”)
Internal registers may be written to the 3 wire μP interface pins (CSN,CCLK and CDTI). The data on this interface
consists of Chip address (2bits, CAD0/1), Read/Write (1bit, Fixed to “1”; Write only), Register address (MSB first,
5bits) and Control data (MSB first, 8bits). Address and data is clocked in on the rising edge of CCLK and data is
clocked out on the falling edge. For write operations, data is latched after a low-to-high transition of CSN. The clock
speed of CCLK is 5MHz(max). The CSN and CCLK pins should be held to “H” except for access.

C Bus Control Mode (I2C = “H”)
Internal registers may be written to I
2
C Bus interface pins: SCL & SDA. The data on this interface consists of Chip
address (2bits, CAD0/1), Read/Write (1bit, Fixed to “0”; Write only), Register address (MSB first, 5bits) and
Control data (MSB first, 8bits). Address and data is clocked in on the rising edge of SCL and data is clocked out on
the falling edge. Data can be written after a high-to-low transition of SDA when SCL is “H”(start condition), and is
latched after a low-to-high transition of SDA when SCL is “H”(stop condition). The clock speed of SCL is
100kHz(max). The CSN pin should be connected to DVDD at I
2
C Bus control mode. The AK4353 does not have a
register address auto increment capability.

* When the AK4353 is in the power down mode (PDN = “L”) or the MCLK is not provided, writing into the control
