Note 22. I2C is a registered trademark of Philips Semiconductors.
Note 23. Data must be held long enough to bridge the 300ns-transition time of SCL.
Note 24. The AK4367 can be reset by bringing PDN pin = “L” to “H” only upon power up.
Purchase of Asahi Kasei Microsystems Co., Ltd I2C components conveys a license under the Philips
I2C patent to use the components in the I2C system, provided the system conform to the I2C
