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 PCLKCRO 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 4-15. I2C Peripheral Module Interfaces

The registers in Table 4-14configure and control the I2C port operation.
