Block  
A. The I2C registers are accessed at the SYSCLKOUT rate. The internal timing and signal waveforms of the I2C port are  
also at the SYSCLKOUT rate.  
B. The clock enable bit (I2CAENCLK) in the PCLKCR0 register turns off the clock to the I2C port for low power  
operation. Upon reset, I2CAENCLK is clear, which indicates the peripheral internal clocks are off.  
Figure 4-17. I2C Peripheral Module Interfaces  
The I2C module has the following features:  
Compliance with the Philips Semiconductors I2C-bus specification (version 2.1):  
Support for 1-bit to 8-bit format transfers  
7-bit and 10-bit addressing modes  
General call  
START byte mode  
Support for multiple master-transmitters and slave-receivers  
Support for multiple slave-transmitters and master-receivers  
Combined master transmit/receive and receive/transmit mode  
Data transfer rate from 10 kbps up to 400 kbps (I2C Fast-mode rate)  
One 16-word receive FIFO and one 16-word transmit FIFO
