    Hello Chen,

    these two tables have tow different functions.

    The 933 Mode defines which clock source is chosen for the normal operations, PCLK or External Oscillator. This one can be chosen as your system requires and it does not affect the 934 Mode settings.

    The 934 Mode defines which data type and frequency mode will be used. Choosing this mode defines the maximum clock used. These settings on the 934 will be transferred via the back channel to the 933 and settled automatically there.
