Notes:
• In 3-wire serial control mode, the AK4492 does not support read commands.
• The AK4492 supports read command in I²C-bus control mode.
• If the address exceeds “15H”, the address counter will “roll over” to “00H” and the next write/read
address will be “00H” by automatic increment function in I²C-Bus mode.
• Bits indicated as 0 in each address must contain a “0” value. Writing after 16H is also forbidden.
Malfunctions may occur by these actions.
• When the PDN pin goes to “L”, the registers are initialized to their default values.
• When RSTN bit is set to “0”, the digital block except control registers and clock divider is reset, and the
registers are not initialized to their default values.
• When the state of the PSN pin is changed, the AK4492 should be reset by the PDN pin.
