Reset and Power Down
The AK4584 has both a power-down mode for all circuits by pulling the PDN pin or a partial power-down mode that is
enabled via an internal register (see Table 22). The AK4584 should be reset once by bringing PDN pin = “L” upon
power-up.

Serial Control Interface
The internal registers may be either written or read by the 4-wire μP interface pins: CSN, CCLK, CDTI & CDTO. The data
on this interface consists of Chip address (2bits, C1/0 are fixed to “00”), Read/Write (1bit), 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 the 16th rising edge of CCLK, after a high-to-low
transition of CSN. For read operations, the CDTO output goes to high impedance after a low-to-high transition of CSN.
The maximum speed of CCLK is 5MHz. The chip address is fixed to “00”. The access to the chip address except for “00”
is invalid. PDN pin = “L” resets the registers to their default values.
