Serial Control Interface
The AK4628A 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. When the state of P/S pin is changed, the AK4628A should be reset by PDN pin.
* Writing to control register is invalid when PDN = “L”.
* AK4628A does not support the read command.
(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).
