4.12 Inter-Integrated Circuit (I2C)
The device contains one I2C Serial Port.

within the device.
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.
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.
