NOTES:
1. These frequencies exceed the upper limit of 100kHz of the I²C-bus specification and cannot be used in an I²C-bus application.
2. At f_OSC = 24 MHz the maximum I²C bus rate of 100kHz cannot be realized due to the fixed divider rates.

NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any conditions other than those described in the AC and DC Electrical Characteristics section
of this specification is not implied.
2. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maxima.
3. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V_SS unless otherwise
noted.
