NOTE:

Ports 1.6 and 1.6 should be connected to VDD through resistors of sufficiently high value such that the sink current into these pins does not

exceed the IOL1 specifications.

Purchase of Philips I2C components conveys a license under the Philips’ I2C patent

to use the components in the I2C system provided the system conforms to the

I2C specifications defined by Philips. This specification can be ordered using the

code 9398 393 40011.
