Mode Control Interface
Some function of AK4366 can be controlled by both pins (parallel control mode) and register (serial control mode) shown
in Table 12. The serial control interface is enabled by the P/S pin = “L”. Internal registers may be written by 3-wire μP
interface pins: CSN, CCLK and CDTI. The data on this interface consists of Chip Address (2bits, fixed to “01”),
Read/Write (1bit; fixed to “1”, Write only), Register Address (MSB first, 5bits) and Control Data (MSB first, 8bits).
AK4366 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 16th CCLK “
↑
”. The clock speed of CCLK is 5MHz (max).

PDN pin = “L” resets the registers to their default values. When the state of P/S pin is changed, AK4366 should be reset
by PDN pin = “L”.
