7.2 I2C Client Interface
The I2C Client interface is a two-wire serial interface consisting of a Serial Data Line (SDA) on pin #16 and a Serial Clock Line (SCL) on pin #17. This interface is used for debugging of the ATWILC3000A.
I2C Client responds to the 7-bit address value 0x60. The ATWILC3000A I2C supports I2C bus Version 2.1 - 2000
and can operate in following modes:
- Standard mode (with data rates up to 100 kbps)
- Fast mode (with data rates up to 400 kbps)
Note: For specific information on the
I2C bus, refer to the Philips Specification entitled,
The I2C-Bus Specification, Version 2.1.
The I2C Client is a synchronous serial interface. The SDA line is a bidirectional signal and changes only while the SCL line is low, except for Stop, Start and Restart conditions. The output drivers are open-drain to perform wire-AND functions on the bus. The maximum number of devices on the bus is limited by only the maximum capacitance specification of 400 pF. Data are transmitted in byte packages.
