Mode Control Interface
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, C1/0; fixed to “01”), Read/Write (1bit; fixed to “1”, Write only), Register Address (MSB first,
5bits) and Control Data (MSB first, 8bits). AK4385 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 CSN “
↑
”. The clock speed of CCLK is 5MHz (max).
PDN = “L” resets the registers to their default values. The internal timing circuit is reset by RSTN bit, but the registers are
not initialized.

*AK4385 does not support the read command and chip address. C1/0 and R/W are fixed to “011”
*When the AK4385 is in the power down mode (PDN = “L”) or the MCLK is not provided, writing into the control
register is inhibited.

For addresses from 05H to 1FH, data must not be written.
When PDN pin goes “L”, the registers are initialized to their default values.
When RSTN bit goes “0”, the only internal timing is reset and the registers are not initialized to their default
values.
All data can be written to the register even if PW or RSTN bit is “0”.
