Serial Control Interface
The AK4120 is controlled via registers. Internal registers can be written using one of two control modes, I2C or 3-wire,
that are selected via I2C pin. PDN = “L” initializes the registers to their default values. When the I2C pin is changed,
the AK4120 should be reset using the PDN pin.
* When PDN= “L”, internal registers cannot be written.
* The AK4120 does not support the read command while using the 3-wire Serial Control Mode.
(1) 3-wire Serial Control Mode (I2C = “L”)
Internal registers may be written to using the 3 wire μP interface pins (CSN, CCLK and CDTI). The data on this
interface consists of a Chip address that is fixed to “10” and a Read/Write status (1bit, Fixed to “1”; Write only).
Also a Register address (MSB first, 5bits) and Control data (MSB first, 8bits) are used. 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)
