I2C buses

Two I2C channels are available on DIDO to provide an interface
to other devices compliant with Philips Semiconductors Inter-IC
bus (I2C-bus™) specification version 2.1. External components 
attached to this 2-wire serial bus can transmit/receive 8-bit 
data to/from the device through the I2C module. The I2C ports 
support standard and fast modes from 10 - 400 Kbps (no 
fail-safe I/O buffers).
A third I2C channel (I2C0) is used for the internal connection 
between CPU and PMIC (please refer to Section 5.2).
