Notes:
• In 3-wire serial control mode, the AK4497 does not support read commands.
• The AK4497 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.
• Data must not be written into 0 bits, TEST bit in “0BH” and registers from “16H” to “1FH”. Malfunctions
may occur if data is written to these bits.
• 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 AK4497 should be reset by the PDN pin.
(Note) The AK4497 is register compatible with the AK4490 and the AK4495.
